BELL- 218 TX
button unit that is marked with the letter 'S'. The ring tone is set to the
'Westminster' tone at the factory. If you wish to change this to one of the
seven other possible tones then press the button ( 1 ) briefly until you hear a
tone from the doorbell unit. Repeat this process until you hear the bell tone
that you wish to use. The last tone played remains in the unit's memory and
is set.
CHANNEL SETTINGS
The unit is delivered from the factory with a certain channel setting. If your
doorbell, for example, rings without reason then it is possible that a similar
unit is being operated in the vicinity on the same radio channel. In this
event, remove the battery for a few seconds and reinsert it. After reinserting
the Battery, the code is changed. For further information refer to the
instruction manual of your wireless doorbell.
CHANGING THE BATTERY
Remove the back of the casing by pressing a small slotted screwdriver
against the notch on the side and lift the casing off in an upward motion ( as
shown in figure 1 ) . Remove the old battery and insert one 3-volt lithium
battery ( CR2450 ) . Ensure that the positive pole ( + ) is facing in the right
direction. Replace the cover by inserting the hooks on the top of the reverse
side and click it into the lower edge.
