10. Cleaning and care
10.1 Cleaning
Warning! To avoid the risk of electric shocks,
injuries and damage:
– Always disconnect the mains adapter from
the power socket before cleaning the device.
– Never immerse the individual parts in water.
Caution! Under no circumstances use abrasive, corrosive
or scratching cleaning agents, as these could damage the
device.
1. If necessary, wipe the individual parts with a damp
cloth.
2. Only use the baby monitor again when all the parts
have fully dried out.
10.2 Changing the battery
The installed 2.4 V 850 mAh Nickel metal hydride battery
(NiMH) may be replaced only by a genuine replacement
battery as used by us. If necessary please contact our After
sales service (see "13. Warranty" on page 60).
1. Remove the battery cover
13 on the back of the parent
unit 1 , by sliding it downwards.
2. Remove the defective battery.
3. Put the new battery in its compartment as indicated on
the unit. There is only one way to attach the plug.
4. Slide the battery cover 13 back onto the parent unit 1 .
5. Initially, charge the parent unit continuously for
14 hours to activate the full battery capacity (see
"7.1 Parent unit" on page 55).
11. Technical data
11.1 FHSS Technology
Frequency Hopping Spread Spectrum (FHSS) is a digital
frequency spreading method for wireless data
transmissions.
This method has several advantages over conventional
radio transmission:
• difficult to intercept the radio signal, because the listener
does not know how the signal is distributed among the
different frequencies and how to correctly reassemble it.
• less susceptible to interference because a given carrier
frequency is always used only very briefly before switching
to another.
Wireless connection 2.4 GHz FHSS
Transmission frequency 2400-2483.5 MHz, < 20 dBm
Number of channels 36 / automatic channel selection
Outdoor range app. 300 m (free field without interferences)
Indoor range app. 50 m
Successful transmission depends on the environment. Walls or trees can seriously
interfere with reception.
