Subject: Re: Oregon TP326 Troubles
In reply to: Joe 's message, "Oregon TP326 Troubles" on Tue 20 Apr 2004; 5:49pm

UnLocking :

"Oregon suggested the keypad lock sequence was : ".. lock or unlock the TP326 by using the UP/DOWN button to avoid accidental pressing. Then, press and hold down MONI(SHIFT), then press CALL (VOX) to lock or unlock the keys."

The new ones (Serial 303 etc.) have a small hole inside the bottom of the battery compartment with a picture of a padlock.

"the little hole accesses a membrane switch and any sharp object poked in here may damage the switch, especially given frequent use."

"If you tap a paperclip onto the switch in the hole, it toggles the "radio" FM and MW modes (that don't work!), and then back to normal. If you HOLD the paperclip in for a couple of seconds, the Keylock symbol comes on, and the keys are locked, but it does not have to display the FM or MW details."

If the usual UnLocking procedure fails, the last resort seems to be a reset : "supply 4.5v across eprom pin 4 gnd,pin 8 +ve,and switch on, I have done 17 of these units with total success"
