Operating with Batteries
When to replace the batteries
When the batteries become weak, the REC/BATT indicator will glow
faintly and the playback sound will become distorted or unstable.
In this case, replace both batteries with new ones.
Concerning the battery life, see “Specifications”.
Operating on House Current
Note on the AC power adaptor
Use only the supplied AC power adaptor (purchased in Canada only)
or the AC-E30M AC power adaptor (not supplied). Do not use any other
AC power adaptor.
Polarity of the plug
(Unified polarity type)
Note
Power will be supplied through the AC power adaptor or the car battery
cord when it is connected to the unit instead of the installed batteries.
Make sure that the AC power adaptor or the car battery cord is
disconnected from the unit when you wish to use the unit with the installed
batteries.
SERVICE NOTE
® Repairing printed resistor
Cut both side of the resistor and solder the carbon resistor
having same value in place of printed one of the conductor side.
1/32W carbon resistor is supplied for the replacing part of the
printed resistor.
Notes on chip component replacement
@ Never reuse a disconnected chip component.

PRECAUTION
1. Clean the following parts with a denatured-alcohol-moistened
swab:
record/playback head pinch roller
erase head rubber belts
capstanidlers
2. Demagnetize the record/playback head with a head demag-
netizer. (Do not bring the head demagnetizer close to the erase
head.)
3. Do not use a magnetized screwdriver for the adjustments.
4. After the adjustments, apply suitable locking compound to the
parts adjusted.
5. The adjustments should be performed with the rated power
supply voltage unless otherwise noted.
