What is M1 M2 M3 on the ambassador 4500 - Cameras

To clear any memory, store the value 0 in it.

They're telling you that you have non-zero values stored in M1, M2, and M3. To clear any one of them, store 0 in it by pressing 0 n where n is 1, 2, or 3. To clear all three of them at once, press ON/AC.

To store numbers into the phone's memory:

Lift receiver - you should hear dial tone. Then, press 'STORE', press key M1, M2 or M3.* Enter the number you wish to store. Then, press the 'STORE' key again. Now, press the memory position you chose above, (M1, M2 or M3).** Replace receiver back on cradle.

To use - lift receiver and press the memory key that was optioned, (M1, M2 or M3). If a numeric key, (1-9), was chosen - press the 'MEMORY'' key then the chosen number.

* To store in numeric 1 - 9, just press the 'MEMORY' key for this step.
** When storing in numeric 1-9, Press the 'MEMORY' key and then the number you wish to store in this step.

Tip: For a phone card, use M1 for the 800 number and M2 for the PIN.

The M1 in the display remind you that the M1 memory contains a number that is not equal to 0. So, to get rid of M1, M2, or M3, you shoild store the value 0 in them.
0 [STO] 1 stores 0 in M1, and thus erases its contents: M1 disappears
0 [STO] 2 stores 0 in M2, and thus erases its contents:M2 disappears
0 [STO] 3 stores 0 in M3, and thus erases its contents:M3 disappears.

Hello,
Your calculator has 3 memories (M1, M2,M3)
To store the 170 in M1 use 170[STO]1
To recall a number from M1 use [RCL]1
To add a number to the content of M1 [2nd][SUM]1 (adds displayed value to contents of M1).
[2nd][EXC] 2 exchanges the value already displayed with the contents of M2:

Hope it helps.

hit "0" then "STO" then "1", repeat except end with "2",then "3"

Clear the display so that zero shows, then press STO M2 to store zero in the M2 registry. Any time there is a non-zero number stored in M1, M2 or M3, you will see those memories in the display to remind you there's something stored. There is no "clear memory" function on the TI-30XA, you have to store zero in the memory to clear M1, M2 or M3 from the display.

One-Touch Dialing
Your phone is equipped with three .One-Touch Priority. keys for
instant dialing (m1, m2, and m3). You cannot store phone
numbers directly into m1, m2, andm3. They are only used
to dial phone numbers stored into memory locations 1, 2, and 3
on the keypad.
1. To instantly dial phone numbers stored in memory locations
1, 2, or 3, simply press m1, m2, or m3. (There is no need to
press talk, the phone will automatically dial.)
2. If no phone number was stored in memory locations 1, 2, or 3
on the keypad, pressing m1, m2, or m3 will do nothing.

I hope this helps.
