Displaying the Signal Strength Level (RSSI Level, BER)
(Maintenance Display)
Maintenance Display
is the function to check the signal strength level (RSSI level), site information, and simplified BER
by displaying them on the transceiver’s LCD as rough indications when structuring a system or executing maintenance of
the system.
Pressing the
Maintenance
key places the transceiver in Maintenance Display Mode.
Or, the transceiver can also be placed in Maintenance Display Mode by selecting “Maintenance” after placing the transceiver
in Menu Mode by pressing the
Menu
key.
About BER
The BER in this function is used for an area check, and for an status check when an abnormal noise sounds.
The area check can also be checked by signal strength, but the signal strength may appear higher if an interfering signal,
etc. are close-by.
Because communication is actually unavailable at the location where the BER deteriorates even if the signal strength is
sufficient, the BER can be used to check an area for actual use, and as a guide to measure the sensitivity capability.
In this way, the purpose of use of the BER in this function differs from the purpose of use of the BER measurement in Test
Mode.

Press the
Maintenance
key.
If the RSSI level is -96 dBm
The transceiver enters Maintenance Display Mode and then the RSSI level
appears. Display of the RSSI level is renewed every 500 ms.
The following operations are the same even if the transceiver enters
Maintenance Display Mode by pressing the
Menu
key:
If the RSSI level is less than -120 dBm
If the RSSI level is more than -70 dBm
For Mobile, “>-80dBm” appears if the RSSI level is more than -80 dBm.
