REPAIR INSTRUCTIONS FOR SLIDE COVER
In some cases 'intermittent audio' or 'no audio' have been observed in NSE-5
phones, because of defective slide cover. Following symptoms can be
observed:
1. Microphone does not work
2. Digital (TDMA) noise in speaker
3. Slide cover falling off
1. Microphone does not work:
Reasons for this;
A. Short circuit between gold lane on slideflex. This short circuit often occurs
in the end of the slide cover, because of metal dust (gold dust) gathering
with too much grease.
Repair instruction:
Take a cotton bud and clean the flex, especially the area in the left bottom
corner (see picture 1)

3. Slide cover falling off:
A reason for this is that the phone has been dropped or hit by something.
Another reason might be that the user has been playing with the slide
(continuous disassembly/assembly)
Repair instructions:
Check the snaps on both sides: if there is no damage on them, put the slide
cover back on the metal slide. If the snaps (just one of them) are damaged
(see picture 3 & 4), then replace the slide cover with a new one, and put it
back on the metal slide.
