Blinking letters on pedometer

Hello there! Assuming your talking about "XtremeMan SOMA BT" I'm not a fan of assumptions but... if this is the device your are referring to then here you go below. If this is not the device you are making reference to, then please respond with the model number and make/brand of the device. Thanks for your visit and good luck.
1. With the unit on or off, plug the included cable
from the USB jack on your computer to the micro
USB jack v on this unit. While charging, the
battery level will be shown by the LED indicators
with the current level LED blinking. When all
the LED indicators light solid, then the unit
is fully charged.
2. If the power level is less than 10%, the left-most
LED indicator will start blinking, which means
that the Soma BT needs to be charged.
Using the Soma BT with a Bluetooth Device
1. Turn on the unit as shown above.
2. Press and hold the Bluetooth button U for
approximately three seconds until a beep
sounds and the right-most LED starts blinking.
3. Within five minutes, select Soma BT from the
Bluetooth List on the external device. See
external device's owner's manual for details.
When paired successfully, the Soma BT will beep
twice and the right-most LED will light

Blinking blue means the HBS in a pairing mode. Go to BT settings on your phone, find your hbs and push "pair". If asked put the code 0000 or 1111.

It means,you'r out of paper.Check the sensor,which register if the paper is in casette

This has got to be the most confusing question... do you mean who replaces the pedometer? like under warranty? You need to see if you have a warranty, and if it is still under the warranty. I would start with asking the place you bought it from. No make, no model, no idea of the age of the pedometer, so not much of an answer.

Pedometers run on a battery, the type depends upon the exact make and model which you have failed to mention.

Many cheap giveaway pedometers are not designed to have the battery replaced but it's usually possible to carefully prise the case apart if it's not screwed together. Some are glued together in which case you'll need a razor saw: if you have to buy a razor saw then it's cheaper to just replace the pedometer. You'll often find that with cheap disposable pedometers that the batteries actually cost more than a complete new unit with batteries included.

More expensive pedometers will always have a clearly defined battery access point, even if it's just a matter of undoing a few screws to separate the casing..

I recommend you backup your favorites.

Then attempt a hard reset.

Finally, replace the firmware and system software using webupdate.
Replacing the system software will most likely correct the malfunctioning keying of letters.

I hope that helps.

when the red light blinks, there will be electric/electrinc circuit failure so get it to a repairer/kodak service.

yes - after setting time for alarm, press mode and set to get alarm icon on screen

On the Sharp copiers when the "ch" is blinking means that the toner cartridge is not in or it may be the wrong cartridge. Some sharp cartridges look alike and will fit into the machine but are the wrong one.

Hope that helps...
