FUNCTION KEY
The (Function) key is used to access the secondary functions marked in Red on the four keys
immediately below the LCD. To select a secondary function, briefly press the key (‘F’ will be
displayed) then immediately press the key labelled with the required function. If no secondary key is
pressed within 10 seconds, the radio will return to normal operation.
The following secondary functions are available.
LOCK (Keypad Lock)
OS/GS (Open/Group Scan)
HI/LO (TX Power)
DUP (Duplex)
KEYPAD LOCK
The key is used to lock the keypad to prevent unintentional key presses from altering your
TX6500S‘s settings. While the keys are locked, only the PTT, On/Off Volume control, LOCK and
Squelch keys continue to function. If any other key is pressed while the keypad is locked, ‘LOCK’
is displayed.
To lock the keys, briefly press the key followed by the key. A high beep will be heard and
‘LOCK’ will appear on the display for several seconds. The keypad will now remain locked even if the
radio is switched off and on again.
To unlock the keys and restore them to normal operation, briefly press the key followed by the
key. A low beep will be heard and ‘ULOCK’ will be displayed for a few seconds.
OS/GS KEY
The key is used to select a scan group for scanning. Available scan groups are Open scan (OS),
Group scan (GS) or Network scan (NETWK).
To cycle between Open scan, Group scan or Network scan, briefly press the key followed by
the key. ‘OPEN’, ‘GROUP’ or ‘NETWK’ will be displayed briefly.
Please refer to the SCANNING section for further details on the operation of each scan group.
NOTE: Network scan is disabled by default and if required, will need to be enabled through the Menu.
HI/LO POWER
The key is used to switch the transmitter power from its maximum level of 5 watts down to 1
watt. Using low transmitter power for short range communications will conserve battery power. If you
need to get the maximum use between charges and you spend a fair proportion of the time transmitting
then selecting low power can increase battery life quite dramatically.
Briefly press the key followed by the key. A high beep will indicate High power is selected
and a Low beep indicates Low power is selected. When Low power is selected, ‘LO’ is displayed.
DUPLEX
Duplex operation allows the TX6500S to operate through repeaters. Repeaters automatically re-
transmit your signal over a wider area, providing greatly increased range.
