OPERATION AND CONTROLS
12
• AVOID DEEP DISCHARGE 
 
Recharge the batteries after each use. The 
two-step fast-charge / trickle-charge 
operation of the SR560 allows the charger 
to be left on indefinitely. ALWAYS recharge 
the batteries immediately after the BATT 
indicator LED on the SR560 turns red. 
Built-in protection circuitry in the unit 
removes the batteries from the load once a 
dead-battery condition is detected. 
Avoiding deep discharge will provide the 
longest battery life - upwards of 1,000 
charge / discharge cycles. 
 
• AVOID TEMPERATURE EXTREMES 
 
When using battery power, operate the 
SR560 at or near room temperature. 
Operating at lower temperatures will reduce 
the capacity of the batteries. As well, more 
time will be required to recharge the 
batteries to their rated capacity. Higher 
temperatures accelerate the rate of 
reactions within the cell, reducing cell life. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
• KEEP THE BATTERIES COOL 
 
When not in use, the SR560 should be 
stored in a cool, dry place with the batteries 
fully charged. This reduces the self-
discharge of the batteries and ensures that 
the unit will be ready for use when called 
upon. A SR560 in storage should be 
"topped off" every three months with an 
overnight charge to maintain its batteries in 
peak condition. 
 
 
Warning regarding battery maintenance 
 
Batteries used in this instrument are seal 
lead acid batteries. With usage and time 
these batteries can leak. Always use and 
store this instrument in the feet-down 
position. To prevent possible damage to the 
circuitboard, it is recommended that the 
batteries be periodically inspected for any 
signs of leakage.
