This can be used to active a PTT on some external radio systems. Audio from the beltpack and local base station’s headset is also available at pin 15 only when QB is active.

Relay = If active, when button C on the beltpack is pressed, a relay closure is activated on the rear of the base station.

RF Meter

This screen displays a larger version of the 5 bars of received signal strength displayed on the status screen. It also displays the receive frequency.

2.Select the RF meter menu with the <UP>/<DOWN> arrow keys and press <SET> to go to the RF meter.

ClearScan™

Press and hold <MENU> + <SET> for 3 seconds to enter the ClearScan™ menu. There will be three option from with to choose from by using the <UP>/<DOWN> arrow buttons and then press <SET>. Those options and the results are explained below.

ClearScan™ Groups

This option scans all the groups in the base station. The group with the highest number of clear receive channels is listed at the top of the list (<UP> arrow all the way to the top). The next group down has the second highest number of clear receive channels and so forth. Channels that clearly have RF interference on them are inverted.

A possible result of ClearScan™ Groups is shown below:

x= No frequency in that receive channel position. It would be dashed lines if examined in the group/channels screen.

4= Interference found on the receive channel during the groups scan.

After a group is decided upon, press <SET> to select that group. A ClearScan™ Channels is now initialed. See ClearScan™ Channels description.

ClearScan™ Channels

This option scans all the receive channels within the base station's currently set group. This scan is also initialed after a ClearScan Groups in order to find the clear receive chan- nels within that group. The receive channel with the least amount of RF noise on it is listed at the far left (<UP> ar- row all the way to the left). The next channel to the right has the next least amount of RF noise on it and so forth. Channel that clearly have RF interference on them are in- verted.

A possible result of a ClearScan™ Channels is shown be- low.
