3. Operating Modes
The VT 9109 has a number of operating modes, including:
• STANDBY
• PHONE
• MEM
• RINGING
• PAGE
• PHONE/PAGE
• MEM/PAGE
• MEM/RINGING
These operating modes can be triggered by any of the following events:
• pressing keys on the handset
• receiving an incoming call from the PSTN
• pressing the <PAGE> button on the base unit
• replacing the handset on the cradle
• removing the handset from the cradle
• a timeout (where appropriate)
For this section, the following definitions apply:
• Number Keys = {<1> <2> <3> <4> <5> <6> <7> <8> <9> <0>}
• DTMF Keys = {<1> <2> <3> <4> <5> <6> <7> <8> <9> <0> <*> <#>}
• Dialling Keys = {<1> <2> <3> <4> <5> <6> <7> <8> <9> <0> <*> <#> <REDIAL> <MEM>}
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 connection, and the handset goes into a sleep sub-
mode 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).
When in the STANDBY mode:
<PHONE> - causes the VT 9109 to go to the PHONE mode
<CHAN> - this key is locked out
<OFF> - series of on hook data send to base and maintains VT 9109in the STANDBY mode
Dialling Keys - these keys are locked out
<REDIAL> - this key is locked out
<MEM> - causes the VT 9109 to go to the MEM mode
Ringing - causes the VT 9109 to go to the RINGING mode
<PAGE> - causes the VT 9109 to go to the PAGE mode
On Cradle - maintains the VT 9109 in the STANDBY mode
Off Cradle - maintains the VT 9109 in the STANDBY mode
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 seized the PSTN connection; and both transmit and receive audio path
open for voice communication. Dialling is also possible while in the PHONE mode.
Pressing the <CHAN> key causes the VT 9109 to seek a new RF channel for operation (refer to section 4.3 for
more details).

Placing the handset into the base unit cradle will automatically release the PSTN connection, and return the phone
to the STANDBY mode (auto hang-up).
When in the PHONE mode:
<PHONE> - causes the base unit to generate a hook flash to the PSTN
<CHAN> - causes the VT 9109 to change to a new RF channel
<OFF> - causes the VT 9109 to return to the STANDBY mode
Dialling Keys - cause the base unit to dial the corresponding digits
<REDIAL> - dials the content of redial buffer
<MEM> - this key work with digit key for memory dialling
Ringing - invalid condition
<PAGE> - causes the VT 9109 to go to the PHONE/PAGE mode
On Cradle - causes the VT 9109 to return to the STANDBY mode
Off Cradle - invalid condition
3.2.1. Dialing Methods
The VT 9109 supports three dialling 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.
Temporary DTMF dialling mode is only available when the default method is set to pulse. In that case, pressing
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 9109returns 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 dialled during the previous call. 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 redial buffer becomes invalid as soon as any of the DTMF keys is pressed, or if
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 is pressed, either using the DTMF keys, or memory-
dialling 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 corresponding to the desired memory location. After the <MEM> key is pressed, only the number
keys (memory locations), the <Phone> key (hook flash) and the <OFF> key (return to the STANDBY mode) will
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.
