On the unit  
•Use only the  
unit. Non-standard cassettes cannot be used because their “L”  
dimension (see illustration) is different.  
When you use the unit in a noisy place, it will stay in the recording  
mode. If the sound is too soft, on the contrary, the unit will not start  
recording. Set VOR to H (high) or L (low) depending on the conditions.

(
M-560V) or BATT (M-455/450) lamp dims.  
•Do not leave the unit in a location near heat sources, or in a  
place subject to direct sunlight, excessive dust or mechanical  
shock.  
For M-650V  
Replace the batteries with new ones when the BATT lamps go  
off and the Elamp flashes.  
Should any solid object or liquid fall into the unit, remove the  
batteries or disconnect the AC power adaptor, and have the  
unit checked by qualified personnel before operating it any  
further.  
Notes  
The unit will play back normally for a while, even after the Elamp  
flashes. However, replace the batteries as soon as you can. If you do not,  
the playback cannot be made with normal sound, noise may be  
recorded and the recorded sound will not be loud enough (M-650V  
only).  
•Keep personal credit cards using magnetic coding or spring-  
wound watches etc. away from the unit to prevent possible  
damage from the magnet used for the speaker.  
When you do not use the unit for long, remove the batteries to  
avoid damage caused by battery leakage and subsequent  
corrosion.  
In the following cases you do not need to replace the batteries:  
if the REC/BATT or BATT lamp flashes with the playback sound  
when you turn up the volume.  
if the Elamp lights momentarily when the tape starts running or at  
the end of the tape (M-650V only).  
if the Elamp flashes during FF (CUE) or REW (REVIEW) (M-650V  
only).  
•If the unit has not been used for long, set it in the playback  
mode and warm it up for a few minutes before inserting a  
cassette.
