I want to get 2 phones,1to connect to landline, and 1 by my bed.

this can be overcome by either running a piggy back connection at the input point of the land line and running the extension wire to the other phone
by buying a cordless phone set ( 2 phones ) and placing the base set at the point where the existing phone is and the other cordless phone in the room
the base phone set connects to the land line and the second phone is by wireless transmission to that base set
all you will need is a power supply for the second phone as it has a charger as a stand for the phone

Will not hold charge / shuts off

the batteries may need replacement. 2 aaa size ni-mh 560 mah 1.2 v are required. or the charger may be defective. If the charging light or the battery bars show up in display when placed in the cradle, the charger may not be defective.

Phone has beep & no dial tone. Screen says its searching

I was unable to locate a manual for your phone online, but can offer some suggestions to solve your problem.

Most cordless phones beep in battery low, out of range, and other situations. Since it is also displaying the "Searching" message, it indicates that it lost its link with the base due to being brought too far from it or the battery power has fallen to low to permit use as far as it may have worked before.

The quick fix is to simply place the phone into the base / charger. This re-establishes a security link between the cordless handset and your telephone line. This is a safeguard that is used to prevent others with the same cordless phone from merely getting "near your base / charger" and gaining access to your dial tone to place calls on your phone line.

If the battery is low, it should left to remain on the base / charger long enough to fully charge the battery. If the battery fails to charge, there may be an issue with the base / charger; but it is much more likely to be a problem with a battery that has reached the end of its useful life (batteries seldom last more than a couple of years and may not last a single year depending on usage). Either condition will require replacement of the faulty device before using again.

If you need more help, you may want to try Thompson Electronics (if purchased prior to 2011) at 800-448-0329 or their website; as it appears GE contracts with them for support after the warranty period.

Good luck!

My telstra 8100 cordless phone keeps showing the word searchingnow i cant do anything with the phone.hope someone can help. Cheers

Place the telstra 8100 handset in the charger. Call any number while the handset is in the charger and it should dial out - you can hear the dial tone now. Take the handset out of the charger and you should be able to call normally.
cheers Matt
