3.1. STANDBY Mode
The STANDBY mode is the idle mode of the VT 9109. In this mode, both the base unit and handset RF
transmitters are turned off, the base unit has released the PSTN connecti on, and the handset goes into a sleep submode to conserve battery power. The handset ‘wakes up’ (turns on its receiver) periodically to check for an
incoming RF link (incoming PSTN call or Page signal).

3.2. PHONE Mode
The PHONE mode is the main operating mode of the VT 9109. In this mode, a RF link is established between the
handset and the base unit; the base unit has sei zed the PSTN connection; and both transmit and receive audio path
open for voice communication. Dialling is also possible while in the PHONE mode.
Pre ss i ng the <CHAN> key cause s the VT 9109 to seek a new RF channel for operation (refer to section 4.3 for
more details).

3.2.1. Dialing Methods
The VT 9109 supports three di alling methods: pulse, tone (DTMF), and temporary DTMF. The pulse or tone
dialling mode can be set as the default dialling method by programming on the handset unit.
Tempor ary DTMF dialling mode is only available w hen the default method is set to pulse . In that case, pressi ng
the <Tone/*> key on the handset will initiate temporary DTMF dialling such that all subsequent digits dialled will
be in DTMF (including <*> and <#>). Temporary DTMF dialling will continue until the VT 9109r eturns to the
STANDBY mode, at which point the default pulse dialling resumes.
During DTMF dialling, the <Tone/*> key will dial the DTMF <*> digit. During Pulse dialling, the <#> key has
no function and will be ignored (even though a key-beep will be generated at the handset).
3.2.2. Redial Buffer
The redial buffer stores the first 32 digits of the number dia lle d during the previous cal l. The number may have
been dialled using the DTMF keys, the <REDIAL> key, the memory dialling feature, or any allowable
combination of these.
The contents of the redial buffer can be dialled to the PSTN by pressing the <REDIAL> key immediately
following the <Phone> key. The redi al buffer becomes invalid as soon as any of the DTMF keys is pre ssed, or i f
the memory dialling feature is used and cannot be accessed until the phone returns to the STANDBY mode.
It is possible to dial further digits after the <REDIAL> key i s pre ssed, ei ther using the DTMF keys, or memorydialling feature. Any suffix digits (including memory dialling) will be appended to the redial buffer.
The redial buffer is stored in the RAM of MCU and will be erased if MCU is reset.
3.2.3. Memory Dialing
Numbers can be dialled out from any of the 10 speed dial memories by pressing the <MEM> key, followed by the
number key corr esponding to the desired memor y l ocation. After the <MEM> key is pressed, only the number
keys (memory loc a tio ns) , the <Phone> key (hook fla sh) and the <OF F> key (r e turn to the STANDBY mode) w i l l
be accepted - the remaining keys on the handset will be locked-out. There is 6 s timeout on the memory-dialling
mode.
It is possible to dial digits before and after using the memory dialling feature; these digits can be dialled using the
DTMF keys, the <REDIAL/PAUSE> key, or the memory dialling feature.

3.3. MEM Mode
The VT 9109 supports three pr ogramming sub-mode s: speed dial programming, tone/pulse sel ect programming.

Any of the DTMF diall ing keys ca n be used to store numbers in the spee d dial memory independe nt of the defaul t
diall ing method. If the default dialling method is pulse when using the speed dial number, the digit <#> will be
ignored and the digit <*> will initiate temporary DTMF dialling.
A pause can be inserted into a memory location by pressing the <REDIAL/PAUSE> digit after the pause is
required for two (2) seconds. A key-beep will be heard with the <REDIAL/PAUSE> key-press, and then again
after two (2) seconds; the second key-beep indicates that a pause has been programmed.

3.4. RINGING Mode
The RINGING mode occurs when a vali d ring signal i s applied to the base unit from the PSTN connecti on. The
base unit establishes a RF link to the handset, and sends commands to the handset causing it to ring (if the ringer is
turned off, the handset will not ring).
