Voice/Speakerphone Controls

Talk/Monitor switch (10)
The T (talk) position gives an off hook condition for dialing and talking as a
common battery telephone. The M (monitor) position removes the transmitter
from the circuit. It provides a high impedance coupling to allow line monitoring
without disrupting conversations or signalling.

The Handset/Speakerphone switch (11)
The Speakerphone and Amplified Speakers provide convenient handsfree
operation. The switch is used to turn the Speakerphone and Amplified Speakers
ON and OFF.

Volume Control (12)
This switch sets the volume control for the Speakerphone/Amplified speakers.
The volume can be set to H (high), M (medium, or L (low). Note that to prevent
acoustic feedback, the test set mutes the regular transmitter and receiver in
Speakerphone Mode and Speaker Mode.

Speakerphone calling
Calls can be made with the Speakerphone ON or OFF by selecting the Talk (T)
position on the Talk/Monitor switch. When making a call in Speakerphone mode,
the numbers dialled can be heard from the speaker providing an audible
feedback to the user.

Battery life
To extend battery life, the speaker will automatically shut off after approximately
five minutes if there has not been a signal greater than -30 dBm in that period.
Any signal greater than -30 dBm resets the timer and keeps the speaker turned on.

Mute switch (13)
The mute switch turns the Speakerphone microphone off for privacy.

Keypad Controls

Polarity
The Polarity LEDs (1) automatically illuminate to show line polarity when off

hook. The green LED will light if the red test lead is connected to ring (negative)
side of the line and the black test lead is connected to the tip (positive) side of
the line. The red LED will light if the test leads are reversed. The LEDs will also
flash during pulse or tone dialing. They are turned off during Speakerphone or
Amplified Speaker mode.

Tone/Pulse
This toggle switch works as a Tone/Pulse switch. In addition, pushing the "*" key
will enable you to temporarily switch between Tone and Pulse without using the
toggle switch.

Storing Numbers
The STO button (3) is used to store numbers in memory. There are 12 total
memory locations (keys 0 through 9, * and #), with each capable of storing
up to 16 digits.

Before storing a new number it is advisable to first clear the memory location to
be used. To clear the memory location, press the STO button twice, followed by
the memory location to be cleared.

To store a number:
1. Switch to T using the T/M switch (10)
2. Press STO
3. Enter the number to be stored
4. Press STO
5. Press the key for the desired memory location.
6. Switch to M using the T/M switch (10)

To store a number while off hook:
1. Connect the test set to the line and receive a dial tone.
2. Dial the number.
3. Press STO twice
4. Press the key for the desired memory location.

Dialing using Recall
The RCL button (4) is used to recall a number stored in memory. After receiving
a dial tone, press RCL and the number key for the memory location. The
number
will be automatically dialled.

Last Number Redial
The LNR button (5) redials the last number called (in either Tone or Pulse mode
) after going on-hook and then back off-hook.

appears RF1.

Manual

Pause
There are some cases where it may be necessary to insert a pause between
digits of a stored number, such as when accessing a trunk through a PBX that
requires a 9 to get out. To store a number with a pause, simply press the PSE
button at the point where the pause is required. For example to store 9-555-1212,
you would enter 9[PSE]5551212. The PSE button inserts a 3.6 second pause.

Operation
" To monitor a line, first set the Talk/Monitor switch to M. Then connect the test
leads to the circuit under test. Monitoring can now be done without disrupting
traffic.

" When testing circuits, CLICKS can be loud enough to cause acoustical shock.
Test sets should not be held closely against the ear. They should be positioned
to rest comfortably on the shoulder, away from the ear or set to Speakerphone
mode.

Maintenance
1. Disconnect clips from any metallic connections before performing any

maintenance.

2. If the test set fails to operate properly at any time, first replace the battery and

retest (see Battery Replacement).

3. Do not use chlorinated solvents on the test set.

Butt Set Trouble Shooting
1. Prokit's Butt Set is a professional telecom tool, especially designed for

checking telecom line. It is not allowed to use under the power source
AC100~125V 50/60Hz or AC200~250V 50/60Hz; otherwise, it may cause the
danger of electric shock or product damage.

2. If there is any crosstalk in application, generally it is the interference from the

telecom line, please set the Speakerphone level control switch (12) in the
position of M or L to reduce the interference; or please check if the alligator
clips are well connected to the telecom line.

3. If any abnormal situation is found while you are using the Prokit's Butt Set,

please test the other telecom line in the different area to identify the possible
defect situation referring to the trouble shooting list below. (Attention! Please
never have the alligator clips connected to the power source for safety reason.)
If the Butt Set still doesn't work after the first step of fix-up, please send back
the product to Prokit's distributor for repairing.
