.. If the status LED blinks red once every five seconds in standby, the battery needs charging. When a low battery condition is detected, the radio will automatically revert to low power when transmitting to help prolong the battery's life. If beeps are enabled, two short beeps will be heard before each transmission indicating the radio has automatically switched to low power mode. Sending a 2-tone/selective call or emergency call Your radio may have been programmed to send a 2-tone or selective call for the current channel. Your dealer or communications coordinator may have programmed your radio to send an emergency call. Please consult your dealer or communications coordinator if you are not sure about the use of the call function. Obviously, you should not send an emergency call unless it is warranted. If a 2-tone or selective Call 1 or Call 2 has been assigned for the selected channel, it may be sent by pressing the PTT button then pressing the upper (Call 1) or lower (Call 2) function button. If your transceiver has been programmed to send an emergency call for the selected channel, it may be sent by pressing the lower then upper function buttons, and holding them pressed for at least two seconds. ! Please consult your dealer or communications coordinator before testing the emergency call function. The radio may be programmed to respond differently when sending an emergency call. Scanning channels If you have more than one channel programmed, your SP-410 / SP-420 / SP-430 / SP-440 may be programmed to allow you to scan them. To activate scan press and release the lower function button. If the scan list has at least two channels the radio will begin checking all channels in the scan list for activity. The status LED will blink amber once every five seconds while the radio is scanning. To turn scan off press and release the lower function button again. If beeps are enabled a high pitched beep will sound when scan is activated and a low pitched beep will sound when scan is turned off. The default scan list is programmed by your dealer or communications coordinator. Your dealer may also have designated a particular channel in the scan list as a priority channel. The priority channel is checked for activity more often than other channels in the scan list. The priority channel may also be checked for activity while the radio is receiving on a non- priority channel. The radio may be programmed to wait a period of time after a receive signal ends. Once the resume timer has elapsed, scanning will resume. This programmed resume timer will also be started whenever the radio has ceased transmitting on a channel. Your dealer or communications coordinator will customize the scan options for your particular situation, so the following paragraphs detail the available options. Busy channel scan If no priority channel has been programmed by your dealer or communications coordinator, all channels in your scan list will be checked for activity, with no preference given to any channel. If activity is detected on a channel the radio will stop on that channel. Depending on programming, the radio may resume scanning after a programmed maximum channel dwell time, even though a signal is still present on the channel. While the radio is stopped on a channel it may be deleted from the scan list by pressing and releasing the upper function button. This function may be referred to as nuisance channel delete. If only one channel is left in the scan list, the radio will automatically turn off scan. When scan is turned off (or the radio is turned off), all channels removed from the scan list using nuisance channel delete will be restored. Priority channel scan If a priority channel has been programmed by your dealer or communications coordinator, the priority channel will be checked more often than the other channels in the scan list. If activity is detected on a channel the radio will stop on that channel. While stopped on a non-priority channel, the radio may be programmed to check for activity on the priority channel. This may be referred to as priority channel lookback, and the receive audio from the non-priority channel will be briefly interrupted while priority lookback occurs. While the radio is stopped on a non-priority channel it may be deleted from the scan list by pressing and releasing the upper function button. This function may be referred to as nuisance channel delete. The priority channel can not be deleted from the scan list. If only one channel is left in the scan list, the radio will automatically turn off scan. When scan is turned off (or the radio is turned off), all channels removed from the scan list using nuisance channel delete will be restored. Transmitting while in scan mode If PTT is pressed while the radio is in scan mode, your dealer or communications coordinator may have programmed one of the following options for the transmit channel: 1. When PTT is pressed, the radio will generate an error beep because...
