The supplied CAT460 flexible antenna is attached here.

POWER SWITCH/VOLUME CONTROL

Turns the transceiver on and off, and adjusts the volume.

PUSH-TO-TALK (PTT) SWITCH

Activates transmission.

SQUELCH (SQL) SWITCH

Sets the point at which random noise on the channel does not activate the audio circuits but a received signal does. This point is called the Squelch threshold. Further adjustment of the squelch control will de- grade the reception of wanted transmissions.

BUSY/TX INDICATOR

This indicator glows green when a signal is being received and red when transmitting.

UP (￿) KEY

Used to select a desired channel. Each press increases the channel number. When held down, the channels increase continuously.

DOWN (￿) KEY

Used to select a desired channel. Each press decreases the channel number. When held down, the channels decrease continuously.

16/9 KEY

Immediately recalls channel 16 from any channel location. Holding down this key recalls channel 9. The 16/9 key is also used to revert to the channel selected before pressing the 16/9 key.

Example: select Ch68, press 16/9 key (Ch16 appears), press the 16/9 key again and Ch68 is shown.
