Jun 15 (Iss. 1.4) Page 52 SPECIAL FUNCTIONS
8 SPECIAL FUNCTIONS
Special functions can be programmed to each of the keys/buttons on the SDP660 Portable Radio
by the FPP. These special functions can be simple short cuts to specific menus or an on/off toggle
facility for specific actions.
8.1 CHANNEL UP AND DOWN
These function keys will change the channel in the upward or downward directions.
8.2 ZONE UP AND DOWN
These function keys will change the zone in the upward or downward directions.
8.3 SCAN ON/OFF
These function keys will start and stop Scanning.
8.4 SKIP
The Skip function removes a scan channel from the scan list if the Skip button is pressed while
stopped on that channel. The channel is only restored to the list when the channel is re-selected.
8.5 TALK AROUND ON/OFF
On a repeater channel only, a Talk Around function key allows the radio to transmit on the base
station’s output channel, so the user can talk directly to other radios on the channel, while the
repeater is out of service or out of range.
When the key is pressed again (or the Channel is changed) the mobile’s Tx channel reverts to its
normal setting.
Talk Around mode is indicating to the user by a double beep at the start of each PTT.
8.6 LOW POWER
The Low Power function key forces the radio to low power. Pressing the function button again puts
the radio back to the power level defined for the current channel. The “forced low power state” is
not affected by channel/zone changes.
8.7 GO TO CHANNEL A, B, C OR D
This function allows specific zones and channels to be allocated to the keys rather than having to
navigate through the menu system or using the ▲ and ▼ buttons.
8.7.1 Go To Contact A, B, C or D
This function allows the first four contact entries to be allocated to the keys rather than having to
navigate through the menu system.
8.8 MENU
The Menu function key is used for accessing the menu system.
8.9 ZONE, CHANNEL, CONTACT AND MUTE
These are specific functions that provide direct access to the ‘Channel’, ‘Zone’, ‘Contact’ and ‘Mute
Adjust’ menus.
