RECEIVER OPERATING INSTRUCTIONS
Before operating a receiver, one or more IFB PTX-3 transmitters must
be placed in XMIT mode, with each transmitter set to the desired
frequency and connected to a proper antenna, audio source, and
power source. The transmitter frequency block must be the same as
the receiver frequency block as marked on each unit.
RECEIVER NORMAL OPERATION (ALREADY PRO-
GRAMMED)
1. Set the Frequency of the receiver to match the frequency of the
transmitter by using the two HEX rotary switches located on the side
of the receiver under the sliding door. The 1.6M switch is for
“coarse” adjustment (1.6 MHz per click) and the 100k switch is for
“fine” adjustment (0.1 MHz per click). Setting both to zero (00) is the
low frequency end of the block and setting both to F (FF) is the
highest frequency end of the block.
2. Plug an earphone or headset into the 3.5mm jack. Be sure the unit
has a good battery.
3. Rotate the knob clockwise to switch the power ON (Do NOT hold the
knob in while switching power ON). The LED will illuminate. Rotate
the knob to set the desired audio level.
4. If channel frequencies have been stored in the memory, change
channels by pressing the knob briefly and release. The LED will
blink the next channel number (frequency) and the receiver will
resume operation on that channel. If no channel frequencies have
been stored when pressing the knob to change channels, the LED
will flash from green to red to yellow to green, indicating no stored
channels and the unit will resume operation on the channel set by
the switches.
5. Whenever power is switched ON, the unit operation defaults to the
channel frequency set by the switches.
PROGRAMMING- ADD A NEW FREQUENCY TO THE
NEXT OPEN CHANNEL
1. Position the receiver at a location within 20 to 100 feet of the
transmitter or transmitters.
2. With the power ON, depress the knob until the LED starts rapidly
blinking, then release the knob.
3. The unit goes into program mode and does a scan/search.
Previously programmed frequencies will be automatically skipped.
When the unit stops on a new frequency audio from the transmitter
will be heard in the earphone and the LED will stop blinking rapidly
and will change to a slow blink mode.
The unit is now waiting for an operator decision. You must now
decide to either SKIP or STORE the frequency (step 4 or 5 below.)
Switching the power to OFF without storing will delete the frequency.
4. To SKIP the frequency, depress the knob briefly and the
scan/search will resume.
