If the problem persists despite trying all of the measures given here, the telephone's rechargeable battery
is defective. Replace the rechargeable battery:
You can purchase a genuine replacement battery from an electronics retailer. Using so-called aftermarket
batteries that are not originals, like the kind available over the internet, may damage your FRITZ!Fon.
Using quick-dial numbers
If you hold down the quick-dial keys on your FRITZ!Fon, you can quickly access various functions and
telephone numbers. You can assign telephone numbers to keys 2 to 9 so you can call these parties even
faster. In addition, you can easily lock the keys on your telephone to prevent entries from being made
accidentally, or you can enable the Do Not Disturb function if you want to temporarily disable the ringer.

2 Assigning a telephone number to a quick-dial number
FRITZ!Fon uses the quick-dial numbers 02-09 from the FRITZ!Box's first telephone book. For example, if
you press and hold down the number 2, the party you assigned the quick-dial number "02" to is called:
1. Click "Telephony" in the FRITZ!Box user interface.
2. Click "Telephone Book" in the "Telephony" menu.
3. Click on the "Telephone Book" tab or the "Switch telephone books" link and enable the option
"Telephone Book".
