P1225 case variation @ accessory plug

[sataraid1]

I have a handful of P1225s that I'm refurbishing with new cases. All of them need new dust caps to cover the mic jack.

The odd thing is, only one radio out of the batch has the threaded socket for the mic retainer. The rest lack this. Yet my service manual shows all variations of the P1225 as having this threaded socket.

When I ordered dust caps, I used 3885771L01, but according to the agent at the shop, it substituted to 3885773L01, which turned out to be the larger cap that does not fit these radios.

Was this a model change during the production run? Are the radios with the set screw older, newer? Was it an ordering option?

If that's the case, can someone let me know if the original part number was the smaller cap? And better yet, can someone help me find some? New or clean used ones, I need several.

As far as that goes, if anyone has a drawer or box full of P1125 case parts (knobs, shells, speaker felts, escutcheons, etc) by all means let me know.

Thanks for any help or info you can offer.

The housing with the threaded insert at the accessory connector is the newer model. It was a revision to resolve the problem with the accessory plug not staying in place. The older model had a slide on retainer that didn't work well.

We don't use any audio accessories with the older model. Just not reliable.

Thanks for the clarification. Can anyone with older documentation find out what the number for the original cap was?

What type of housing? basic? display? keypad?

I think there were at least 2 P1225 series. ZPC (older) and ZRC (newer with the threaded insert) (letters in the model#).

I have an old part# for the old style basic housing. 1580671E05. It's NLA from Motorola. I have a note in an old manual that indicates that this was an upgrade from the first version housing that was a 1580671E01

I also see some housing kits for the "ZRC" model
HLN9901A REPLACEMENT HOUSING KIT - 2 CHANNEL - ZRC MODELS NLA from Motorola
HLN9902A REPLACEMENT HOUSING KIT - 16 CHANNEL - ZRC MODELS NLA from Motorola

I see a HLN 3065 housing kit that changes a basic radio to a DTMF radio

New style audio accy retainer is a HLN9900
Old style audio accy retainer is a HLN9523 (Still available)

I just re-read your post and realized it was the dust cap you're looking for.

Try 3880679E01 for the accy jack dust cap for the housing without the threaded insert. Still available from Motorola. Less that $1.00 ea

More info:

I just found an old service bulletin that explains about the different versions of housings. While not directly related to the original question, I thought I would post it for future reference.

There were 2 early versions with 2 types of retainer clips. One slid on and one clipped on with 2 ears.

SERVICE BULLETIN SRN-I0001
SUBJECT: P1225/P1225LS Housing and Accessory Retainer part numbers.
Purpose: Advise Radius Resellers of replacement housing kit part numbers and accessory retainer compatibility for the following models.
Models: P1225/P1225LS portable models
Issue Date: May 17, 2000
To: All Radius Resellers
Issue: Compatibility of housing kits and accessory retainers of newer “ZR” and older “ZP” models.
Definition: May 19, 1999 Radius released the “ZR” P1225 radio models. The “ZR” Model replacement housing kits and accessory clamps are not compatible with
older P1225/P1225LS models.
Action: Reference the following chart when determining compatibility of housing kits and accessory retainers for specific model numbers.
OLD MODEL # HOUSING KIT # NEW MODEL # HOUSING KIT#
P93ZPC90A2_A HLN9631B * P93ZRC90A2_A HLN9901A **
P93ZPC90C2_A HLN9632B * P93ZRC90C2_A HLN9902A **
P93ZPD90C2_A HLN9633B * P93ZDC90C2_A HLN9903A **
P94ZPC90A2_A HLN9631B * P94ZRC90A2_A HLN9901A **
P94ZPC90C2_A HLN9632B * P94ZRC90C2_A HLN9902A **
P94ZPD90C2_A HLN9633B * P94ZRD90C2_A HLN9903A **
P94ZRH95A2_A HLN9906A ** P94ZRF95A2_A HLN9905A **

* USE ACCESSORY RETAINER - HLN9738A
** USE ACCESSORY RETAINER – HLN9900A

NOTE: The HLN9738A is not compatible with early A Version “ZP” P1225 housings.
The old model number P1225 radios can have an A Version or a B Version housing depending on the manufacture date. If you have an early A Version “ZP” housing, it must be retrofitted with a B Version housing kit to be compatible with the HLN9738A.

Please reference the option jack diagram #1 for Version verification.

Diagram 1 shows an accy jack labeled "A" version with a rectangular recess around the 2 pins and a second accy jack labeled "B" version with 2 slots (on on each side of the pins) for an audio accy retainer with 2 ears to clip into.

That's good news. Thanks for the correct part number, and for the background information. I appreciate the help.

While we're on the subject of case swaps, what's the secret to getting the battery latch plate out of an old case?

[CircleBat]

Pry it open with a small screwdriver.. These casings will flare up around the bottom latch area or will crack if its dropped too many times.. these were horrible radios with either water getting into the radio causing water damage on the board or the cases will flare up on the bottom from being dropped. That was why Motorola discontinued or limited parts for this radio and is no longer supported. Lotsa leaky caps on the component board causing headaches with troubleshooting.

I'll have to experiment on one of the cases that is too far gone to salvage. It seems to me that with the black plastic thumb tab attached, there's no way to get the metal plate and springs to slide out of the shell without breaking it. Can the black thumb tab be pried off of the plate without breaking it?

Fortunately for my purposes, the P1225s are excellent radios. They receive very very well, can be very affordable if you shop around.

Again, if anyone has any case parts they'd like to unload, or even some radios that are electronically shot but have decent cases, let me know.
