Subject: MOD for STANDARD C156A Date: Fri, 23 Apr 1999 10:22:26 -0500 From: Michael Harbour Please read through the entire procedure before actually performing ANY of them... Keep in mind, all memories will be deleted when modification complete. 1) Remove battery pack from radio 2) Remove the two screws on the back of the radio (not the belt clip ones, the other ones) 3) Gently (very gently) squeeze the very bottom of the radio (the plastic part, the met part is too hard to bend out) so that the front panel can be separated from the back panel, you'll notice you are relieving two clips. 4) Continue to lift the front panel off by using the top as a lever sort of, you may have to wiggle things around to get the two halves apart. Don't worry, there are no wires or ribbon cables to break, just parts to loose... 5) Before proceeding, look out for the following... The red power button - don't loose it. Keypad zebra strip - don't loose it. 6) Looking at the PCB on the back half of the radio, you'll see at the top, the display, below that, in the middle, a contact for the speaker, and below and to the right of that, another contact, of which are housed in a plastic holdy-thingamajig. Immediately below the bottom-right-most speaker contact you should see a small diode and a vacant diode place right above that one... 7) What you want to do is remove the diode so there are 2 vacant places. Immediately to the bottom left of this diode are two parts, one a diode, and another which looks to be hanging off the diode. You do NOT want to disturb these two parts, the other tiny part looks to be added in after Standard realized they made a mistake or something... 8) I'm pointing out these for two reasons, one is so you know it's not these you want to take out, it's the diode between them and the speaker contact. And secondly is to warn you that if you do disturb these other parts it will result in a PLL unlock which renders the radio useless... 9) Once you've removed the proper diode, you may re-assemble the radio. You'll want to make sure that the red power button is sitting properly, and the zebra strips are in place, if you don't think they've moved, don't bother them. 10) Replace the front panel by getting the top in position first and then whie holding the top together, close the radio from the bottom, you may need to wiggle things a little to get it back together, and gently squeezing the tabs at the bottom again while closing it may make things easier when you're just about done. 11) Replace the two screws that escure the two halves together. Do NOT tighten the screws too tight as you risk cracking the crappy plactic standoffs inside. 12) Upon inserting the battery back into the radio, the radio should automatically reset when it turns on. If you don't feel comfortable with this, don't do it.
