2. Description
The MPG01 is ideal for installation, maintenance and all aspects of
connection to tele-phone lines. The linesman’s test set is housed in a
high impact and highly visible colored rubber housing. The housing is
designed to give the operator maximum grip. The rubber keypad is
set in a border designed to prevent more than one key being pressed
at any one time.
The following characteristics make the MPG01 special:
• Operation in DTMF or PULSE
• Temporary activation of DTMF dialling
• 20 button keypad with dedicated function keys
• Memory dialling of 10 stored numbers (Two- Touch)
• Last number redial in DTMF or PULSE (31 digits)
• Three-tones ringer
• FLASH button
• MUTE key - microphone disabled
• High Impedance listening function - MONITOR - also without dis-
turbing ISDN or Data Transmission signal
• Polarity check with button - LED red/green (optional)
• Key to increase reception volume by 5,4 dB
• Modular insertion of cord (easily replaceable)
• Overvoltage and overcurrent protection
• Specifications according to national standards.
3. Operation
xDSL: At the first use charge the batteries for about 10 hours as ex-
plained in paragraph 3.14.
3.1. Switch on and off
To turn MPG set the switch to ON.

7
To turn set the switch to OFF..
xDSL: When MPG xDSL goes off-hook generates a tone. If the bat-
tery level is low no audio alarm will be generated (see paragraph
3.13).
3.1. Checking talk battery on the line
MPG looks for talk battery on line.
Follow these steps:
• Clip the test set to Tip and Ring of a subscriber loop.
• If the voltage on the line is above 66Vo ∿the test set
emits an audio alarm.
• If the voltage on the line is above 110Vo ∿the test set
emits an audio alarm and will not go off-hook.
3.2.1 xDSL: Checking voltages on line
The test set checks voltages on line: an audio alarm signals the
presence of AC voltages. Follow these steps:
• Clip the test set to Tip and Ring of a subscriber loop.
• Set the switch to ON.
• By no voltage the right LED lights up blinking red
• By voltage greater than 66V turns on the right LED solid
red and the test set will not go off-hook.
• If data is detected, the test set will not go off-hook and the
right LED lights up solid green with a continuous tone.
• To go off-hook with data present press the GS button,
(see § 3.4 and 3.5).
The test set will not go off-hook if the line voltage exceeds 110 V DC,
the right LED lights up blinking red and an alternating tone advise the
operator. To turn the safety function off, turn off the test set.
If the voltage on the line is above 66Vo ∿,
this is potentially dangerous to you and the
test set. If you encounter this, carefully
remove the test set’s clip leads from the line.
Be sure to hold the clip leads by their
insulated boots and avoid touching the clip
lead’s metal parts with your hands.

8
ATTENTION: Any communication, on an active data line, disturbs
the transmission with possibility of data loss. To communicate we
recommend to connect the test set via an ADSL filter.
3.3. Polarity check
When connected to a line, MPG01 can check polarity by pressing
POL. The LED will go red for reversed polarity and green for correct.
The MPG is not polarity sensitive therefore correct or inverted con-
nection does not affect the instrument’s performance. Follow these
steps:
• Switch off MPG and connect to the line
• Press POL BAT key: by correct polarity left LED will light up
solid green. Right LED will light up solid red whit reverse po-
larity (red clip connected to “b” (-) and black clip to “a” (+))
Attention: The input impedance of MPG during polarity check is ap-
prox. 5 kΩ. Normally it is bigger than 1MΩ (Position OFF). Checking
on a live line could disturb data transmission.
3.4. High Impedance Listening (Monitor)
MPG01 allows for high impedance listening without disturbing con-
versations or call signals. Follow these steps:
• Switch off MPG and connect to the line
• Switch ON and select MON (Fig. 2/a),
xDSL: ON is confirmed by tone and blinking green right
LED.
• In the presence of digital signals, you will hear the character-
istic hiss.
• If the battery is low no tone will be emitted by switching ON
(see paragraph 3.13).
• Switch OFF MPG when finished.
MPG automatically power-down after 5 min xDSL: 2 minutes to con-
serve battery power. To power-up switch to OFF and to MON.
3.5. Answer an incoming call
The call will be signalled by a 3-tone buzzer. In order to talk switch
ON xDSL: MPG emit a tone .

9
Perform the line check previously (see paragraph 3.1) !
3.6. Selecting a number
MPG01 allows for both dial signalling PULSE or TONE thanks to the
PULSE-DTMF switch. Follow these steps:
• Choose DTMF or PULSE using the switch (fig. 2/e)
• Switch on MPG
For the use in special PBXs you can shift from PULSE DTMF without
interrupting the call (not vice versa). Select PULSE with the PULSE
key (fig. 2/e).
• Switch on MPG
• Select the number desired
• Press key and continue selection in DTMF.
To switch OFF MPG01 move the switch ot OFF or press the R key.
In DTMF mode, the and # keys are active.
MPG01 stores the last number dialled in either PULSE or DTMF
mode and it can be redialled independently of the original dial mode.
To activate LNR, turn off the butt set and procede as follows:
• Choose DTMF or PULSE using the switch (fig. 2/e)
• Switch on MPG
• Press the LNR key
• Conversation
Attention: In the case of mixed dialling, (DTMF and then PULSE or
vice versa), the number is not stored.
3.7. Two-Touch Memory Dialling
The storage memory has 10 abbreviated numbers which can be se-
lected with the 1... 0 keys. The * and # keys are not active. After hav-
ing commenced automatic dialling, it is possible to dial other access
numbers, for example, for special internal numbers. Follow these
steps:
• Choose DTMF or PULSE using the switch (fig. 2/e).
• Switch ON
• Press MEM key and select the desired memory location
(1…0) to call a number
• Conversation

10
3.8. Volume Boost
To increase the audibility in very noisy areas or in the case of long or
poorly insulated phone lines, the MPG has a facility for increasing
the volume (only when switched on) by 5,4 dB. To return to the origi-
nal volume level, re-press the VOL key or turn the instrument off.
Follow these steps:
• Conversation
• Press the VOL key to boost volume
• Press the VOL key to return to original level
When switched off MPG returns to the original level.
3.9. Disabling the microphone (MUTE)
In particularly noisy locations, it could be helpful to eliminate sidetone
by disconnecting the microphone. Follow these steps:
• Conversation
• Press the PROG MUTE key
At this point, pressure on any key will de-activate the disabling of the
microphone. Switching off the MPG will de-activate MUTE.
3.10. Headset (Opzional)
Plugging in a headset will switch transmit and receive function from
the handset to the headset.
3.11. Adress book storing
MPG01 allows for the memorisation of 10 numbers which can be re-
called by the 1 to 0 keys. To insert new numbers in place of old ones
simply reprogram the new number: the old one will automatically be
cancelled. Follow these steps:
• Switch ON MPG
• Press PROG MUTE key to store in
• Press MEM key followed by a number (1…9) to assing a
memory location
• Dial the phone number you want to store
• Store the number by pressing PROG MENU key.
