66 ENVOY™ TRANSCEIVER REFERENCE MANUAL

Manually tuning the antenna

WARNING: Before using the antenna system see the safety information provided.

NOTE: If the transceiver is connected to an automatic tuning antenna, it tunes

the antenna automatically when required.

You may need to manually tune the antenna if you are receiving on a new channel, or

if you want to check the SWR value for the antenna.

To manually tune the antenna:

 Press

TUNE.

The SWR, battery voltage, and type of antenna tuner are shown on the screen.

 Hold down PTT to start the tuning process.

The transceiver makes a series of short beeps.

An SWR of less than 2:1 is acceptable.

NOTE: If PTT is held for more than 2 minutes, tuning is automatically

aborted. The transceiver displays a message to inform you of

this, makes an error beep, and returns you to the screen from

which you began.

 Release PTT to stop tuning.

The beeps cease and you are returned to the screen from which you began.
