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.

nNote: 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 congurations 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.
