A 2702A AM/FM RDS Tuner
SLEEP FUNCTION:
Press the SLEEP button on either the front panel or the remote control, and the sleep playback timer will activate and show
'SLEEP 90 MIN' on the top line of the LCD. The sleep timer begins from 90 minutes, and with each press of the SLEEP but-
ton, decreases the timer in 10 minute steps, with 10 minutes being the shortest sleep timer period.
The sleep time will flash for five seconds and then select the last time that was displayed and start counting down to zero
with the radio playing the tuned frequency. The unit will automatically power off to standby once the countdown timer
reaches zero.
When active, the remaining SLEEP time will be displayed on the top line of the LCD, and it will only be removed momentarily
by pressing the MO-ST button. The sleep function is cleared if the SLEEP button is pressed when the sleep timer is showing
the minutes remaining, without flashing, on the top line of the LCD. Once the unit is off, press SLEEP again to power the
unit back up. 'SLEEP 90 MIN' will again appear on the LCD, and can be deactivated as described above.
NOTE: AM radio is only broadcast in mono in Australia. Some low-power FM stations, especially those with frequencies 88
MHz and below, are also only broadcasting in mono. You cannot force a mono-only transmission to be received in stereo. If
the FM stereo signal is weak, the unit automatically enters mono mode and MONO is displayed on screen. This tuner does
not have a signal strength indicator light or bar on the LCD.
RDS INFORMATION: These are the codes that are decoded by the RDS function in this tuner: PS (Program Station), PTY
(Program Type), RT (Radio Text), CT (Clock Time) functions. If an FM station is not transmitting RDS codes, then when you
press the RDS button on the remote control, the bottom line of the LCD
will show 'PS NONE, 'PTY NONE', 'RT NONE', and 'CT NONE'.
