Life of Backup Battery (Clock Error)
1) The indication of the life of backup battery
When turned on JAX-9B and “Clock error” message is displayed on the LCD, it means that the
backup battery has run out. In this case, replace the battery by referring to Section 5.3.
NOTE
•
If the electronic power supply to JAX-9B is suspended with run-out backup battery,
the internal clock loses accuracy.
Set the time of internal clock again when JAX-9B is turned on.
•
If a GPS receiver is connected to JAX-9B, the “Clock error” message will not be
indicated because the time of the internal clock is set by the GPS data.
•
The backup battery backs up the internal clock only. Therefore, the registered
frequency channels and timer programs are not cleared even if the battery runs out.
The life of the battery is approximately 5 years.
