4.5 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 BERby displaying them on the transceiver’s LCD as rough indications when structuring a system or executing maintenance ofthe 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 transceiverin Menu Mode by pressing the Menu key.About BERThe 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 issufficient, 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 TestMode.Analog Conventional, P25 Conventional, NXDN Conventional, and DMR Conventional systems1 Press the Maintenance key.If the RSSI level is -96 dBmThe transceiver enters Maintenance Display Mode and then the RSSI levelappears. Display of the RSSI level is renewed every 500 ms.The following operations are the same even if the transceiver entersMaintenance Display Mode by pressing the Menu key:If the RSSI level is less than -120 dBmIf the RSSI level is more than -70 dBmFor Mobile, “>-80dBm” appears if the RSSI level is more than -80 dBm.Maintenance ----12 : 34 AMRSSI Level -96dBmBackBER 0.0Maintenance ----12 : 34 AMRSSI Level dBmBackBERMaintenance ----12 : 34 AMRSSI Level > -70dBmBackBER 0.04 TRANSMISSION/ RECEPTION4.5 Displaying the Signal Strength Level (RSSI Level, BER) (Maintenance Display)Common FUNC (K, F)/Ver 2.20 83CONTENTS INDEX
