BASIC OPERATION
The IQ335 can be used in the same way as a normal telephone; simply lift the handset to answer an
incoming call, or lift the handset and dial on the keypad to commence an outgoing call. Please refer to
other sections for more about Handsfree, Headset, Caller ID display and Memory operations. The
telephone will also operate in a basic mode when mains power has failed and if batteries have not been
fitted (the telephone will automatically power up approximately 1 second after lifting handset). If 3 x AA
alkaline batteries (not supplied) are fitted in the absence of mains adaptor or during mains power
failure, they can provide up to one month’s support of all functions.
