Replacing the Real-time Clock Battery
•
Only service personnel should replace the real-time clock battery.
• There is a risk of explosion if the used battery is replaced by an incorrect type.
• Dispose of the used battery according to the battery manufacturer's instructions.
A 3.6V lithium battery provides power to the real-time clock when the SM65 is not powered
from a DC power system. The real-time clock battery may need to be replaced because of its
life span (approximately 11 years).
The battery can be replaced with a Tadiran TL-5902/s, or equivalent, ½ AA non-rechargeable
lithium battery.
