Symptom...... when turned on it does not automatically start to scan without hitting scan button.
Solution..... put scanner into scanning mode and leave on until battery goes completely flat, then turn radio off. When next charged up and turned on it should automatically start scanning, one could also put the scanner into non scan or search mode on turn on by same method. Note this procedure, for some strange reason, will not work by reducing voltage on a variable PSU to simulate flat batteries.
Symptom...... No receive or very poor
Solution...... If radio has been dropped then the nicad pack will have hit T1 quite hard and possibly damaged it. The damage may not show up so change the item and with a little tune up all may be ok again.
Symptom...... Poor receive sensitivity
Solution...... Replace capacitors C1 and C2 (both 33uf) on the DC DC board which is to be found on the underside. Note that the 7000 suffers other problems often due to the electrolytic caps drying out....worth checking the relevant ones first.
Symptom...... Poor RX or TX
Solution...... The screws holding down both boards never seem to be tightened very well so check these first and then put a dab of the girlfriends nail varnish on to prevent them working loose again. If they are very loose it is worth checking that the solder joints on the chassis mounted ICs are all ok. In fact resolder all of them just in case they are cracked.
Symptom...... Fails to retain memory.
Solution...... Try not to allow the battery to go completely flat whilst the set is turned on. The reason being that when the nicads are fully discharged then the radio draws from the memory back up supply, when that is flat all memories are then lost.
