- Selectors 1 and 2 are applicable only to models equipped with PictBridge.
- Selector 4 is applicable only to models equipped with cordless handset(s).
- Selectors 5 through 7 are applicable only to models designed for the UK market.
- Selector 8 is applicable only to models designed for the Chinese market.
- Selector 1 and 2: PictBridge command delay time
These selectors specify the PictBridge command delay time that applies when the
machine responds to the digital camera connected via PictBridge during negotiation. If the
machine fails to receive data from the digital camera, change the delay time.
- Selector 3: More CNG detection cycles in user-friendly reception
If CNG detection fails even after adjustment of selectors 4 and 5 on WSW26, try adding 2
more cycles to the permitted number of CNG detection cycles.
- Selector 4: Cordless handset ID recovery
When this function becomes operative, if the cordless handset ID number registered on
the main board does not match that registered on the cordless board, the cordless handset
ID number registered on the main board will be automatically written onto the cordless
board.
- Selectors 5 and 6: Caller ID tone alert detection time length (Not used)
In the event of a false detection of a caller ID tone alert, adjust the detection time length.
- Selector 7: Caller ID mild pulse transmission (Not used.)
If a caller ID (number display) cannot be displayed due to mild pulses transmitted after
detection of tone alert, use this selector so as to make it impossible to transmit mild
pulses.
