RPX6500 P25 MOBILE RADIO - USER MANUAL
33
5.12. MODE MENU
The Mode menu is used for changing from one radio to another, such as Private Mobile
Radio/Land Mobile Radio (PMR/LMR) mode to P25 or MPT1327 trunking.
From the
Setup
menu, use the / keys to scroll through the sub-menus and, with the
Mode
menu option displayed, press the
OK
key to access the Mode screen.
When the
Mode
screen is displayed, use the / keys to scroll through and select the required
operating mode, such as APCO P25, PMR or MPT Trunking.
When the required mode is displayed, press the
OK
key to select that operating mode. The radio
will then display the default screen for that mode.
Keypad shortcuts can be used to change modes from the keypad as follows:
• PMR (*60#)
• P25 (*80#)
• MPT Network 1 (*71#)
• MPT Network 2 (*72#)
5.13. RSSI MENU
The RSSI screen displays the received signal strength in dBm. When the radio has been correctly
calibrated, the reading is typically accurate to within ±2 dBm between the range of −120 dBm
and −80 dBm. For example, −90 dBm is a strong signal and −120 dBm is no signal.
On digital channels, the RSSI screen also shows the Bit Error Rate (BER). RSSI and BER are
typically used to indicate signal quality.
