Introduction
The JSD TestPhone AM5 Tone Amplifier product provides a means of tracing the
audible signal generated by the TG5 Tone Generator product across a copper cable
network. The product features five (5) sensitivity levels with selectable band-pass
filtering and either contact or inductive pickup of the audible signal which is
amplified and reproduced on the internal loudspeaker or external Headset. Digital
signals [25-250kHz] present on the copper cable network are also identified and
indicated with both audible and visual indicators. The product also features ‘qTrace’
technology which allows the individual discrimination and visual indication of up to
four ‘qTrace’ tones.
Powering `ON` the Probe
The AM5xs is switched `on` by pressing the [ON/OFF SENS+]
button for two (2) seconds, whereupon a BEEP will be
generated, the amplifier is switched on at the maximum
sensitivity level and the ‘ON LO BAT’ indicator will flash slowly.
Normal Tone Tracing (Audio Indication)
To trace the tone bring the probe tip close to the wire and listen
for the tone being reproduced in the loudspeaker.
Band Pass Filter
To activate the internal band pass filter (attenuating signals
below 800Hz and above 1500Hz) switch `on` the AM5xs by
pressing the [ON/OFF SENS+] button for two (2) seconds and
continue holding the button for a further three (3) seconds (5
seconds in total). Confirmation of the activation will be the ‘ON
LO BAT’ indicator flashing fast. To deactivate the band pass
filter switch the AM5xs `off`.
`qTrace` Tone Tracing (Visual Indication)
Trace the signal by bringing the probe tip to within 100mm of the
wire and observing the ‘qTrace’ indicators on the AM5xs. A
maximum of four (4) ‘qTrace’ tones may be identified.
This function will be particularly useful when used in conjunction
with a number of TG5xs units to identify individual pairs.
Range
The AM5xs will detect a standard tone generated from the
TG5xs at 12 miles and q Trace Tones at up to 15 miles.
Sensitivity
The AM5xs is switched on at maximum sensitivity level. The
sensitivity may be reduced by momentarily touching the [ON/
OFF SENS+] button. There are five levels of sensitivity before
the unit will revert to the highest setting. To prevent distortion,
only use a level adequate to hear the tone.

Data Circuits
If the AM5xs is presented to a circuit that is carrying data, the AM5xs will identify
the presence of the data by illuminating the ‘DATA’ indicator and producing
a BEEP-BOP tone in the loudspeaker every two (2) seconds.
Headset Operation
A Headset 17A or 18A Safety Helmet Version may be inserted into the rear
socket of the AM5xs. Inserting either headset will switch on the AM5xs if not
already active, and will mute the internal loudspeaker.
Powering `OFF` the Probe
To switch `off` the AM5xs the [ON/OFF SENS+] button should be touched for
longer than two (2) seconds, at which point the amplifier will shut down and the
`ON LO BAT’ indicator will be extinguished. Should the AM5xs t remain active
for longer than five (5) minutes with no button activity then it will automatically
shut down to conserve battery power.
Battery
Insertion
The product is energised upon insertion of a PP3 battery and will ‘sleep’ in low
power mode until the Probe is switched on. Access to the battery compartment
can be gained by removing the two screws on the back of the unit. Insert one
(PP3/6LR61/1604A Alkaline type) into the battery compartment. The
compartment is polarized to prevent wrong polarity. If the unit is not going to be
used for a long period of time remove the battery.
Replacement
Should the internal 9V battery be low and require replacing, the product will give
a steady illumination on the ‘ON LO BAT’ indicator and produce a BEEP-BEEP-
BEEP audible indication every ten (10) seconds.
Additional Information
 The q Trace function is based on the DTMF (Dual Tone Multi Frequency)
system used on all modern day telephone networks to communicate number
entry when making a call to the local exchange and therefore dial a telephone
number.
 The conductive tip is the slimmer tip and fitted on the AM5 and the inductive
tip can be found separately in the product packaging.
