on the right-hand side panel. On the GS-MPI005 mobile phones, it is located on the
front panel. The headphones output is designed to drive high impedance
headphones. Use of other types of headphones will significantly reduce battery life.
VISUAL INTERFACE
Each mobile phone unit has a standard 4x3 keypad, a large green “DIAL” push-
button and corresponding “OFF-HOOK” LED, and a large red “HANG-UP”
push-button and corresponding “ON-HOOK” LED. The DIAL push-button is
used to dial a phone number entered on the keypad, or to answer an incoming call.
The HANG-UP push-button is used to end a call, reject an incoming call, or to
clear a number that has been entered incorrectly.
When the unit is turned on, it will check if the PIN code is enabled. If it is, the
phone will quickly flash the
“SOUNDER” LED four times, every three seconds.
This prompts the user to input the four digit PIN code in order to unlock the phone.
When the PIN code has been successfully entered, or if no PIN code was set on the
SIM card, the red ON-HOOK LED will flash, indicating that the unit is attempting
to register with a GSM network. Once registration is complete, the ON-HOOK
LED will be on solid and the OFF-HOOK LED will be off. This is the phone's idle
state, indicating that it is on-hook, and ready to dial or receive calls.
When a phone number is entered on the keypad and the DIAL push-button is
pressed, the ON-HOOK LED will be turned off and the OFF-HOOK LED will
start to flash, indicating that the phone is off-hook, and waiting for the phone at the
other end to start ringing. When this happens, the sounder will play a slow ringing
cadence, and the OFF-HOOK LED will flash in-time with the cadence. When the
remote phone is picked up, the OFF-HOOK LED will be turned on solid,
indicating that a call is in progress.
When an incoming call is received and the phone is on-hook, the ON-HOOK LED
will remain on, the sounder will play a fast ringing cadence, and the OFF-HOOK
LED will flash in-time with the cadence.
If a keypad button is pressed during a call, the phone will generate the
corresponding DTMF tone.
MEMORY SLOTS
Each mobile phone unit has nine numbered memory slots, plus one redial memory
slot. These are accessed using three yellow buttons:
“REDIAL” , “RECALL” and
“STORE” . These three buttons can only be used when the phone is on-hook.
Pressing the REDIAL button will cause the phone to go off-hook and dial the last
number dialled. To store a number in a memory slot, type the number on the
keypad and press the STORE button, then press a button between 1 – 9 to select a
memory slot. The OFF-HOOK LED will quickly flash twice, indicating that the
number was successfully stored. To dial a number stored in memory, press the
RECALL button, then press a button between 1 – 9 to select a memory slot. The
