Channel Master Rotator System (9521A) - Manual (Page 2)

and have it inspected by a service technician before further
use. Liquids, rain or excessive moisture may cause electrical
shorts which can result in fire or shock hazards. Never operate
the control near water, such as a swimming pool, etc. or near a
bathtub, sink, laundry tub, or in a wet basement.
14. Cleaning
Unplug the control before cleaning. Use a slightly damp (not wet)
cloth. Do not use an aerosol directly on the control since it may
over spray and cause electrical shock.
15. Performance Change
Whenever the unit exhibits distinct change on performance,
unplug the control and call your dealer or service technician.
16. Servicing
Any attempt to dissemble the control or drive portions of the unit
may expose you to high voltage or other hazards. Observe all
cautionary labels, warnings and safeguards.
17. Damage Requiring Service
If the control has been dropped or the case has been damaged,
fire, and shock hazard may exist. Unplug the control and have it
checked by a service technician before use.
18. Replacement Parts
When replacements parts are required, have the service
technician verify that the replacements used have the same
safety characteristics as the original parts. Unauthorized
substitutions may result in a risk of fire or electric shock, or other
risks.
19. Safety Check
Upon completion of any service or repairs to the unit, please
ask the service technician to perform routine safety checks to
determine that the unit is in a safe operating condition.
20. Lightning
For added protection of the control during a lightning storm or
when control is to be left unattended for an extended period of
time, unplug it from the wall outlet and disconnect the rotator
cable. This will prevent possible shock, fire hazard and damage
to the control due to lightning storms or power line surges.
21. Rooftop Installation
Always use extreme caution when installing a rooftop antenna
and rotator system to reduce the risk of falls. Wear rubber-soled
shoes and use a sturdy ladder. Do not install on a windy day or
when the roof is wet or is covered with ice or snow.

CONTROLLER COMPATIBILITY
If purchased separately, the Model CM-9537 controller may be used
with the following rotator drive units:
Channel Master Models: CM-9500, 9510(A), 9512, 9513, 9515(A)
Radio Shack ® Model 15-1225
If you are upgrading an existing installation with Model CM-9537
controller, skip to controller installation.
ROTATOR INSTALLATION
1. Determine proper size number of rotator cable from chart.
Three conductor cable is suitable, but if four conductor cable is
used, connect both conductors 3 and 4 to terminal 3 on the drive
and control.
*NOTES: Attach 3 and 4 conductors to No. 3 terminals on control and drive.
2. Install drive unit. On new drive units, arrow on mast support
should be aligned with arrow shaped mast stop on housing.
Install drive unit with arrows pointing south. Using a short piece
of mast (3 feet or less), install the antenna to the drive unit
aiming the antenna south. When desired channels are close to
or on opposite sides of the north end stops, the antenna may
be installed pointing north. Note, however, that the antenna
will be pointing in the opposite direction from that indicated on
the control. An alternative means of setting up is to perform a
synchronization of the drive unit using the controller. Then set up
the antenna pointing north. Ensure power is disconnected from
the controller when making antenna adjustments.
See Fig 1 and 2.
Do not mount citizens band base station antennas on top of
a standard mast mount drive unit. Mast support may become
overloaded in high winds.
3. Connect rotator cable to drive unit terminal board. See Fig 3.
CAUTION: When using jacketed cable, be sure jacket of cable passes
thru the grommet to avoid moisture collection in the cable.
4. Attach rotator cable and antenna cable securely to mast or tower,
and pass through building to TV or FM set.
NOTES: See Fig A of the Important Safeguards section regarding
grounding of the lead-in cable for lightning protection.
CAUTION: Before disconnecting old control box, make
note of each wire color and the corresponding
terminal connections. To reduce the risk of electric
shock, do not remove cover. No user-serviceable
parts inside. Refer servicing to qualified service
personnel.
CONTROLLER INSTALLATION
1. Determine the AC supply voltage and frequency in your country.
The US, Canada, Japan, Taiwan and South America are
generally 120 VAC Hz. Europe, Africa, Australia and Asia (except
above mentioned) are generally 230 VAC 50 Hz. Your power
company will advise. Ensure the supplied wall plug power supply
voltage has the same input voltage as your household supply
(±10%). If not, contact your dealer.
2. Plug the power supply into the controller and the household
supply. Observe the digital diagnostic display.
It should display:
• 60H (or 50H in 50 Hz countries)
• HH1 (to use with the supplied handheld remote control)
If the above are not correct refer to Appendix A to change.
3. Disconnect the wall plug supply at the wall outlet. Connect the
cables between the controller and drive unit. See Fig B.
4. Reconnect the AC supply to the controller. After 5 seconds it
will switch off. Switch back on by pressing any key on the front
panel or handheld remote control. Perform a synchronization by
pressing the sync button on the left of the front panel. This takes
slightly over one minute. The unit may now be operated from the
front panel using the up and down controls.
5. Digital Compass
This feature operates as follows:
The display 000 to 360 degrees where:
• 000 is North (fully CCW viewed by a bird)
• 090 is East
• 180 is South
• 270 is West
• 360 is North (fully CW viewed by a bird)
HANDHELD REMOTE SETUP
1. Install 2 AAA batteries in the handheld remote.
2. Check operation by pressing the
POWER button and observing
the display. If it does not function, check for HH1 in power up
diagnostic display. If the display is HH2, refer to Appendix A
to change.
3. The UP and DOWN controls will move the antenna position (the
same as the front panel controls). Alternately, a location may be
accessed directly using a 3 digit compass location. Example,
press 090 for East, 225 for South-West, etc.
4. Programming Preset Locations
This is the most popular mode of operation, 69 preset locations
(01 to 69) allow location numbers to be the same as TV channel
numbers if desired.
a. Find best signal using UP and DOWN controls.
b. Decide on a memory location, eg. 27.
c. Press 27 UP 27.
(Locations 01 to 09, eg. 05 may be programmed by either
05 UP 05 or 5 UP 5.)
d. Location is now memorized.
5. Accessing a Preset Location
As an example, to access location 27, press 27. Display will
flash “ c27”, then show compass bearing while the antenna is
moving. It will become steady “ c27” when it arrives.
(Locations 01 to 09, eg. 05 may be accessed as either 05 or 5).
6. Displaying Memory Locations/Status
From the handheld remote control, press 99 UP. Then observe
the display. Each programmed location is shown, followed
by its digital compass location. Additionally setting of power
frequency, handheld, autosync and timeout are shown.
A typical display might be:
60H 60Hz power c05 270 Compass bearing for c05
HH1 Handheld 1 c11 090 Compass bearing for c11
to on Timeout on c17 270 Compass bearing for c17
888 End of diagnostics 35 35 moves before a resync
Syn on Autosync on
7. Deleting Programmed Locations/Reset
Press 91 DOWN form the handheld remote control.
CAUTION: Use this command with care as ALL memory locations will
be deleted. This will also set autosync off and timeout on
8. Synchronization
Press the SYNC key on the left of the front panel or 00 Down
from the handheld. A counterclockwise movement is performed
to synchronize the control unit with the drive unit for proper
operation. Synchronization takes slightly over one minute.
After severe storms, or an extended period of use, the rotator
may appear to position the antenna incorrectly. First try pressing
the SYNC key to re-synchronize the system. If this fails, the
antenna or drive motor may be misaligned on the mast. You may
either go to the antenna and re-orient it, or reprogram the control
unit to correspond to the new antenna orientation.
9. Auto Synchronization
The unit may be set up program a sync command automatically
after 50 pre programmed moves. This feature is switched on (or
reset to 50) by pressing 98 UP. It is switched off by pressing
98 DOWN. Check to see if active by pressing 99 UP (Display
Status) and observing “ SYn on” or “SYn OFF”.
10. Timeout
The unit may be set to switch off after 8 minutes of no activity
by pressing 97 UP. This feature is deactivated by pressing 97
DOWN. Check to see if timeout is active by pressing 99 UP
(Display Status) and observing “ to on” or “to OFF.” The unit
