• The R250s PRO is a mobile phone, specially designed to be used when
working outdoors. Thanks to its rugged design the R250s PRO is very
resistant to external influences such as dust, rain and shock.
• The R250s PRO is the first mobile phone which supports GSM Pro. GSM
Pro is an extended feature of the GSM network, which supports group
calls and call monitoring. (GSM Pro requires a GSM Pro subscription.)
• The R250s PRO has an vibrating call alert, which means that the phone
vibrates when you receive an incoming call or message. This is a useful
function when you are working in a noisy environment, where you
cannot hear the phone signal.
• When you work in a noisy environment, you can use Ericsson handsfree
equipment in combination with ear protection equipment. At an incoming
group call, the call is answered automatically and you will hear the conver-
sation in the earpiece.
• Key pad lock. The key pad lock prevents accidental dialling, which could
happen if you keep your phone attached to your belt. The key pad remains
locked until you receive an incoming call. While the key pad is locked,
you can still use the Push-To-Talk button on the left side of the phone for
entering the phone book.
• Alert button. The R250s PRO is equipped with an alert button on the top
of the phone, which makes it easy to call a pre-set alert number.
Note! Please read the chapter “Guidelines for Safe and Efficient Use” on
page 112, before using your mobile phone.
