Operator Maintenance
Cleaning
Occasionally the Digital Clock/Timer and the Control Station will need to be cleaned. Dampen a soft, nonabrasive cloth with
alcohol or a mild detergent.
Do not use abrasives or solvents! Gently wipe the exteriors of the units with the cloth.
Battery Maintenance
The Digital Clock/Timer uses a single 9vdc Ni-Cad battery rechargeable via an on board charger. This battery retains the time
of day and timer counts when 120vac power is lost. If each in a series of 120vac power losses occur for a similar length of
time, the battery can be conditioned to provide only that amount of backup capacity. This phenomenon is called “memory”
effect. The Ni-Cad battery’s “memory” can be erased by deeply discharging the battery and recharging it.
It is recommended that the operator remove 120vac power from the Digital Clock/Timer once per year for at least four hours.
n Note: There is no 9v battey in the SQA261RSAES clock. Only the SQA261RSAEA clock it is connected to has a battery.
System Maintenance
The Digital Clock/Timer and ATSTCS Control Station have been manufactured for years of dependable, reliable use. However,
to assure the reliability of this product, it is recommended that the Digital Clock/Timer be tested at least every six (6) months
with the Control Station and Code Blue contact for operation in accordance with wiring configurations used.
WARNING
Replace the battery only with a 9v Ni-Cad battery.
Do not replace with a regular (primary) 9v transistor
battery (i.e., zinc carbon battery, alkaline battery)!
An incompatible battery may leak or explode,
causing equipment damage and/or personal injury!
If battery must be replaced, contact American Time
at 866-748-3796.
