Kenwood TM-V708A instruction manual Reverse Function, Automatic Simplex Check ASC

Page 37

REVERSE FUNCTION

The reverse function exchanges a separate receive and transmit frequency. So, while using a repeater, you can manually check the strength of a signal that you receive directly from the other station. If the station’s signal is strong, both stations should move to a simplex frequency to free up the repeater.

AUTOMATIC SIMPLEX CHECK (ASC)

While using a repeater, ASC periodically monitors the strength of a signal that you receive directly from the other station. If the station’s signal is strong enough to allow direct contact without a repeater, the ASC indicator on the display begins blinking.

Press [REV] (1 s) to switch the function ON.

Press [REV] to switch the Reverse function ON (or OFF).

“R” appears when this function is ON.

Note:

If pressing [REV] places the transmission frequency outside the allowable range, then pressing Mic [PTT] causes an error beep to sound; transmission is inhibited.

If pressing [REV] places the reception frequency outside the allowable range, an error beep sounds and no reversal occurs.

You cannot switch Reverse ON or OFF while transmitting.

While direct contact is possible, the ASC indicator blinks.

To end this function, press [REV].

Note:

Pressing Mic [PTT] causes the ASC indicator to quit blinking.

ASC does not function if your transmit and receive frequencies are the same (simplex operation).

ASC does not function while scanning.

Activating ASC while using Reverse switches Reverse OFF.

If you recall a memory channel or the Call channel that contains Reverse ON status, ASC is switched OFF.

ASC causes receive audio to be momentarily intermitted every 3 seconds.
