[comp.dcom.telecom] Audiovox CMT Series Program Codes

DREUBEN@eagle.wesleyan.edu (Douglas Scott Reuben) (01/26/91)

Here's what I know about programming Audiovox CMT400, 405, 450, 550,
605 and BC-40/BC-45 phones. The instructions may also work on other
models, as all Audiovox (and perhaps other brands?) phones seem to
follow the same procedure.  If anyone saw my last posting on this a
while back, this list is more or less complete (which my last one was
not), so this should supercede any previous postings on the subject by
me.

Without further delay, here's how to program the phone:

1. Turn on the phone.

2. CLEAR out the display (hit CLR)

3. If it has never been programmed, you LOCK code is "000".

4. Enter your LOCK code (usually last 3 digits of your mobile number).

5. Enter FUNC, then "#", and then "1". 

You should now be in program mode. You will see the first three digits
of your phone number as display item #1. (Thus, if your number is
555-1212, you will see something like: "C1 555". C1 is the item
number.)

Here's a table of the different locations:

1. FIRST 3 digits of phone number		3 digits
2. LAST  4 digits of phone number		4 digits
3. LOCK Code					3 digits
4. Area Code					3 digits
5. Home Area System ID				5 dig.,usually "00xxx"
6. Horn Alert (0=disable, 1=enable)		1 digit (0/1)
7. Hands-Free Speakerphone (0=disable, 1=en.)   1 digit (0/1)
8. End-to-end signalling (0=off, 1=on)		1 digit (0/1)
9. Repertory Mark (0=ff, 1=on)			1 digit (0/1)
10.Group ID Mark				2 digits
11.Access Overload Class			2 digits
12.Station Class Mark *				5 digits
13.Local Use Mark (allow local calls only?)	1 digit (0/1)
14.MIN Mark					1 digit (0/1)
15. (not alterable by user, depends on SYS ID)  .......
16. (not alterable by user, depends on SYS ID)  .......
17. Function Mark:                   		3 digits
	a. No functions: 		0 0 0
	b. Preferred System Lock 	0 0 1
        c. Automatic Lock *		0 0 2
	d. Call Timer Beep *		0 0 4
	e. Home / Roam inhibit		0 0 8
	f. Automatic Cell-Site Redial	0 1 6
18. Reserved for future use			.......
19. Reserved for future use			.......
20. Inhibit SYS-ID (IE, block calls in SYS ID#) 5 digits (ie, SYS ID, 00xxx)
21. Horn Alert Turn-Off Timer *	(01-31 hours)	2 digits
22. EMR Turn-Off timer * (01-31 hours)		2 digits
23. Reserved for future use			........
24. Call-Timer Reset code (just use LOCK code)	3 digits
25. Reserved for future use			........
26. Depends on all other settings, not alterable by user.

* = For CMT-550 and CMT-605 only, these features are not available 
    (as far as I know) on earlier models.

You can "move" back and forth between items by pressing the "*" or the
"#" keys.

After you ALTER any item, make sure you press the STORE (STO) key.
This will store your new entry into permanent memory. You must do this
even though your new entry shows in the item line; if not, the
previous entry will remain once you re-start your phone.

When you have STOred all the new items, and wish to end the
programming session, pres: FUNC and SND to write the data into the
phone (NAM). After this, press FUNC and CLR to re-start the phone. You
may also just power it down and then turn it on again. Your phone will
now have the new values which you have programmed in. If you decide
you don't wish to change the info after all, just press FUNC and CLR
(or turn it off/on) without pressing FUNC SND first.

I've found this pretty easy to do, and I manage to change from one
system to another in about 20 seconds. You really don't have to look
at EVERYTHING. All you need to do is enter a new phone number, and
that's it. The System ID code is NOT SENT OUT, no matter what some
paranoid cell co. may say.

Thus, enter the program mode, change locations #1, #2 and #4 (press
"#" or STO to skip over #3, your lock code, unless you want to change
that), press FUNC and SND, and then FUNC CLR, and you are set!

(Note: if you change from the "A" system to the "B" system, or the
other way around, you will have to change the SYS ID code, OR use your
A/B switch to get from one system to the other. This is because the
phone "knows" to look for either the "A" or "B" system first by
whether your SYS ID code is ODD or EVEN.  (A systems = ODD, B systems
= EVEN, so Metro Mobile, the "A" in CT is 00119, while SNET, the "B"
in CT, is 00088.)

I've found that it is even useful to change the SYS ID code while
roaming, to the roaming city's code, so that I will KNOW when I am
using some other nearby system and thus will not incur extra daily
charges. (... in addition to the one I am already paying for roaming.
So let's say I went to Allentown, PA; I would set my SYS ID to be
00103. Thus, while I am in the Allentown system, the ROAM light would
be off. As I moved to the Metrophone/Philadelphia system, the ROAM
light would come on, telling me that if I make any additional calls, I
will pay another roamer surcharge since I am in a new system. Very
useful if you don't know the exact coverage of a system in an area.)

Guess that's it. If you have any questions, let me know, and I'll see
if I can help.
