9.0 Maintenance 
9.1  Battery Warning and Battery Replacement if you are using the 
SREL.BAT battery 
In case the battery capacity is no longer sufficient, a Smart Relay can issue a battery 
warning as follows: 
SREL, SREL.ZK, SREL.ADV 
  Internal LED blinks 8 times each time you operate the transponder and before 
the relay is switched.  
If you are operating with a battery, you should make sure that this LED can be 
seen from the outside.   
Only SREL.ADV 
  External LED blinks 8 times or external buzzer beeps 8 times, each time you 
operate the transponder. 
Approximately 100 operations are possible after the battery warning, so you 
should replace the battery as soon as possible.
