50b.
The Timex Message Mate came in models 150a and 150b. You can find out about all of its functions by consulting the above manual. Travel alarm clock recorder.

easiest way to set clock time. Remove AA battery's if installed.
Unplug Clock from AC. Wait a few seconds. Then replug clock into AC power. Clock will now flash 12:00. Press hours button until correct time is set PM has led on AM has Led off. Set minutes to correct minutes. Then press alarm reset / power/mode button. Wait a few seconds and display will show correct time. Now you can put the AA batteries back in.

I'm afraid you can't because this is not a workshop, but have you tried a watch/clock repairer or jeweller who may have a part which will fit it, or look on ebay for one, either new or for spares. Also you don't state your location (e.g U.K. or USA) so hard to advise further. You could also contact timex directly (google timex contact us) but the address depends on your location.

No! the backup should be automatic, check to make sure battery is good before you return the item.

When you are setting the alarm on the wacky wake-up timex alarm, if you keep pressing FWD, you will see a small PM in the bottom right hand corner. When the PM sign is gone, you will now that it is set to AM.

Hello
Here are the instructions for your clock-radio.

Installation

1* Remove unit and all packing materials from the carton. You should save packing

materials in case unit needs to be returned for service. If you do not wish to save the

materials, please dispose of them properly.

2* Place the unit on a stable, level surface, close to an AC outlet, out of direct sunlight,

and away from sources of dust, dirt, heat, water, moisture, vibration, or magnetic fields.

3* After installing the batteries (see below) and reading the Maintenance notes, plug the

AC cord into an outlet.

"Sure Alarm" Battery Backup Installation

It is strongly recommended that 2 "AA" batteries be installed into the unit, as directed below,

in order to activate this product's "Sure Alarm" Battery Backup feature. (The model should

come with two batteries already installed.) In the event that the AC power cord is disconnected

or a power failure or other interruption occurs, the "Sure Alarm" Battery Backup will maintain

clock and alarm settings for the life of the battery, ensuring that the alarm (buzzer only) will

sound at the set time. During any interruptions the time and alarm settings will be saved

and automatically restored when AC power is again active.

1* Gently turn the unit over and remove the battery

compartment door.

2. Install 2 "AA" batteries (alkaline is recommended for

longer life), while making sure that the + and - ends

match up with those inside the battery compartment.

3* Slide the battery compartment door back on, making

sure the door locks into place, and gently return the
unit to its upright position.

I have an old Lorus travel alarm LHL008N-F and need to know what battery size it uses.

Is it electric or battery operated? Check cables and battery.

I lost my manual also so had to resort to relentless trial and error.
The problem with the alarm is that it is too easy to turn it on.
The 1 and 2 buttons on top of the unit with the alarm clock symbol turn each alarm on or off. Your only cue is on the display in the top line of the display which will have a bell followed by “RADIO” or “SOUNDS”, if the alarm is armed. If you see this symbol and want to disarm the alarm, press the 1 or 2 alarm button according to which alarm was on the display. It’s just as easy to turn the alarm back on either deliberately or accidently
Enter Alarm Setting mode by holding the 1 or 2 alarm button for about 2 seconds.
Display will flash – in this mode you will be able to do the following
Date Set Button – changes between Everyday/Mon-Fri/Sat-Sun
Arrow Buttons – adjust the time setting
Alarm 1 (Radio):
Mode Button – changes between AM/FM1/FM2
1-6 Buttons -- changes between stations
Alarm 2 (Sounds):
Mode Button – changes between SD1/SD2/SD3/SD4/Buzzer
If you don’t change any settings for about 5 seconds the unit exits the alarm setting mode.
Timex already has your money so I guess they are not motivated to publish their manual.

quickly press alarm 1 button to deactivate it when the radio and everyday or mon-fri icons are gone the alarm is deactivated. do the same for alarm 2 button and the sd1-4 or buz icons disappear.
