Replacing The Battery - Conrad Electronic RM 50 Bedienungsanleitung

8. Replacing the battery

With conventional devices you only notice flat batteries because the device
no longer functions (e.g. with a radio or a remote control).
With such an important device such as a smoke detector, this
could have fatal consequences!
The smoke detector therefore emits a brief chirp sound (see section 7 c), if
the battery level is too low, simultaneously with flashing of the indicator lights
/LED.
Then replace the 9V compound battery by a new one immediately.
Proceed as follows to replace the batteries:
• Rotate the smoke detector in a counter clockwise direction and take it off
the lower cup.
• Remove the spent battery from the battery compartment and release the
battery clip from the battery.
• Connect a new 9V block battery to the battery clip of the smoke detector
observing the correct polarity and insert the battery into the battery
compartment.
After inserting the battery, the red indicator light /LED flashes roughly every
32 seconds.
• Lock the smoke detector into the locking lug of the pedestal by rotating
counter clockwise till the smoke detector engages with an audible click.
For safety reasons, the housing cannot be locked without
batteries!
The life of a new high value 9V alkaline compound battery can be
several years.
For reasons of safety, replace batteries every 12 months. The
"old" batteries can then be used in non-critical devices (e.g.
clocks, remote controls etc.).
