4.3 Tone

The wireless terminal supports many kinds of indication tones. These tones sound through the

buzzer installed in the wireless terminal. The situation which tone is generated is as the followings;
 Keypad Tone

When pressing a key, the tone sounds.

 Warning Tone and Conformation Tone

In many situations, these tones are provided as indication or warning to a user according to
each situation.

▶ Error indication tone

When a user does invalid operation, it is generated. There is no message displayed on

the LCD.

▶ Low battery warning tone

If battery voltage level is decreased to less than 2.3V±0.1, it is generated. A block in a low

battery icon on the LCD is blinking in every second and this tone is generated once in
every 20 second until battery voltage level reaches over 2.3V±0.1 by recharging the
battery. When a user puts the wireless terminal on the charger provided by LGE, this
tone and the blinking low battery icon are disappeared. If battery voltage level is under

2.2V±0.1V, power will be turned off automatically to protect circuits of the wireless
terminal without low battery warning tone as soon as pressing the power button to turn on
(It is called by ”Auto-power-off” function). It should be recharged.

▶ Out of range warning tone

When a user is about to get out of a coverage of the subscribed system, “OUT RANGE”
message will be shown shortly on the LCD with warning tone.

▶ Call-connection confirmation tone

When an wireless channel between the wireless terminal and the subscribed system is

established, it is generated. Once pressing button, the wireless terminal tries to get
a wireless channel. At this time,
channel is established, this tone is heard and

▶ Power-off conformation tone

When the wireless terminal is turned off, it is generated.

 Ring Tone

When a wireless terminal gets an incoming call, it is generated. A user can make the
volume level up and down from level 1 to level 7 in an idle state. The incoming call ring
rhythm (CO line call and intercom call, separately) can be selected by a user among 9 ring
rhythms. The default ring rhythm is selected to normal ring rhythm. In the state that vibrator
function is enabled, when a call is reached to the wireless terminal, ring tone can’t be heard
but a user recognizes the phone’s ringing by phone vibration.

Phone
