RPX6500 P25 MOBILE RADIO - USER MANUAL
54
7.11. RESET
The reset function is usually assigned to F6 and performs several tasks. In order of priority, Reset:
• Stops Alerts (if any alerts are sounding)
• Performs a Backspace (if there is a user entry pending)
• Switches back to the Main Menu (if in a lower menu)
Rest is used in text entry modes such as Phonebook Edit and Text Messaging for backspacing.
7.12. SCAN
The Scan key starts and stops the scan mode on a channel that has been associated with a scan
list and enabled for scanning. Scanning will be indicated to the user with a rotating arrow icon.
Scan is supported in both analog and digital mode.
If scan is enabled for the current channel in the current zone and auto scan is not enabled, then
start scanning the channels defined in the current channel’s scan group.
The second press of the scan key will turn scanning off.
Note.
If Auto-scan is programmed for that channel, the Scan key will not function.
7.13. SCAN EDIT
This key is used to enter the Scan Edit menu, where the members of a scan group can be added
or deleted.
7.14. SCRAMBLER (Analog)
This function enables transmitted voice to be scrambled in order to prevent radios without a
scrambler from listening in on the conversation.
This low security form of encryption is sufficient to make speech unintelligible to other casual
listeners. However, it does not offer high level security as other radios programmed with a
scrambler function will be able to unscramble it.
Scrambler is supported in analog mode only.
The speaker sounds a “bip-bip” tone when PTT is pressed to indicate the scrambler is active. The
Scrambler On/Off state is reset to
Off
at power-up and channel change.
The first press of the function key enables scrambler mode. The second press restores the
channel to normal (clear) mode.
7.15. SKIP
The Skip function key is used to temporarily remove members from a scan channel. The removal
is temporary until the channel is changed.
7.16. SQUELCH (P25 CONVENTIONAL)
The Squelch mode is used to selectively receive P25 signals. It has three modes, Monitor, Normal
and Selective. When set to Monitor, all P25 traffic on that channel will be heard, subject to
presence of encryption. Normal mode will hear all P25 traffic with the correct NAC code.
