Product Manual

Operation
The SARC radio is stored in a hard-fronted PVC pouch to protect the unit from damage and to
prevent the accidental operation of the push buttons. The radio should always be replaced with
the pouch writing to the front, ensuring the hard front is placed correctly. To remove the radio
from the pouch, release the strap and break any seal that may be through the pouch eyelet.
Pull out the radio by the aerial and turn on by pressing the ON button. Electrical noise may cause
a faint hiss to be heard if it is above the internally set squelch setting. A green light on the front
panel will indicate the receiver is operating.
(Note: the green lamp was not present on units prior
to serial number 11-35-0125).
To transmit voice, press the PRESS TO TALK button and speak into the front panel in the area
labelled SPEAK HERE. The lamp on the front panel will change to a red colour.
Volume and squelch control levels are only internally accessible and are normally preset by the
factory. The squelch circuitry is carrier activated only which means that nearby electrical
interference may open the squelch from time to time. This can be reduced or eliminated by the
squelch adjustment at the penalty of reduced receiver sensitivity. On transmit, modulator audio
should be present in the headset.
To turn the radio off press the OFF button.
