The R250s PRO is equipped with an

, located on the top of

the phone next to the antenna. See “Overview” on page 4. Alert calls are eas-

ily made by pressing and holding the alert button for one second. If the call

cannot get through the phone automatically re-dials the number up to ten

times.

When you buy your phone the alert number is set to the international emer-

gency number 112. This number can be changed if you prefer another alert

number. This may be useful if e.g. you work in an area where your own organ-

ization’s rescue service can reach you faster.

For more information on how to change the alert number see “Alert Button”

on page 46.

Note! The talk group numbers are provided by your service administrator. For

more information, please contact your service administrator.

The phone book makes it easy to set up a call to your talk groups. Instead of

having to remember the phone number and entering it by using the keypad,

you simply recall the number from the phone book by pressing and holding

the

button when the phone is in standby. When you find the

number you want to call, press

to make the call.

The talk group numbers are stored in the same phone book as the one you use

for storing your own, personal phone numbers. See “Your Personal

Phone Book” on page 33. This means that you may not be allowed to store

your personal phone numbers in the memory positions used by your service

administrator. If you try to store a phone number in a position that you are not

allowed to use, you are prompted to store the number in another position. For

more information on how to store phone numbers see “Storing a Number

Together with a Name” on page 35.

Making and receiving group calls is similar to making and receiving ordinary

mobile phone calls.

Note! We recommend that you set the phone to Push-To-Talk mode before you

make or receive a group call.

You can only call a group of which you are a member.
