Transmit level setting

Make a call to another radio and confirm that your voice can be heard in the
remote radio. The level of your voice can be adjusted by inserting a screwdriver in the slot marked RADIO
TX LEVEL, this can be reduced if you voice is received at a particularly high or distorted level or it can be
increased if you voice is feint.
Radio PTT socket

The PTT (Press to talk) socket allows connection to a press to talk switch on a short
cord so that the radio can be set to transmit whilst connected to the Terraphone. PTT is disabled when
the speaker is switched off.

Mobile phone connection / Level setting
–
The 3.5mm jack socket on the back of the amplifier
marked MOBILE can be connected to your mobile phone. (Suitable leads and adapters can be purchased
from Terratrip or your local dealer). Adjust the amplifier for normal operating levels and then make a call
with your mobile and set the volume on the mobile to give the required level in the headsets. The small
“DIP” switch marked MOB OUT on the rear panel can be set to reduce or increase the received level if
required. A similar switch marked MOB IN can be used to set the microphone level INTO the mobile phone.
This can be switched ON to reduce the mic level if excessive background noise or distortion is heard at the
remote phone and should be left switched OFF if your voice is too feint.
We hope you enjoy your new Terratrip product, please contact Terratrip or your local dealer if you
require any help.
