supply is restored after a power failure or unplugging the unit.
Readjust the clock as follows.

Perform "Setting the clock" from step 1. If the time display is flashing, step 3 (for
selecting the 24-hour or 12-hour display) will be skipped.

"0:00"

The 24-hour display will appear.

(0:00 - 23:59)

(AM 12:00 - PM 11:59)

"AM 0:00"

Note that this can only be set when the unit is first installed or it has been reset. 

Press the TUNING/TIME (  or  ) button once to advance the time by 1 hour. 
Hold it down to advance continuously.

When the 12-hour display is selected, "AM" will change automatically to "PM".

Press the TUNING/TIME (  or  ) button once to advance the time by 1 
minute. Hold it down to change the time in 5-minute intervals.

The hour will not advance even if minutes advance from "59" to "00".

The clock begins counting from "0" seconds. (Seconds are not displayed.) 
The time display will disappear after a few seconds.

Sudden temperature changes, storage or operation in an extremely humid environ-
ment may cause condensation inside the cabinet (CD pickup, tape heads, etc.) or on 
the transmitter on the remote control.
Condensation can cause the unit to malfunction. If this happens, leave the power on 
with no disc (or cassette) in the unit until normal playback is possible (about 1 hour). 
Wipe off any condensation on the transmitter with a soft cloth before operating the 
unit.

Many potential problems can be resolved by the owner without calling a service tech-
nician.
If something is wrong with this product, check the following before calling your autho-
rised SHARP dealer or service centre.
