2.7 TPT OPERATION
The TruLink network is designed to operate with one unit functioning as a MASTER and all other
units as SLAVES. The MASTER broadcasts received audio from one slave TPT to all other SLAVE
TPTs on the wireless network, as well as the wired ICS. If no TAP or DPT is in the network, then
one TPT must be set to act as the MASTER. The following paragraphs describe the TPT operation
without a TAP in the network. For operation with a TAP, see Section 4.
2.7.1 Introduction to TPT Man-Machine Interface
The user interacts with the TPT through the keypad and headset audio. The keypad accepts input
from the user. The TPT advises the user with audio as either tones or pre-recorded voice (SynVoice)
through the headset.
In general, the user initiates a command by pressing the M key. This starts an audio menu. By
repeatedly pressing the M key, the TPT will respond with the next menu item. Upon reaching the
desired item, the * key is used to cycle through the options (settings) available for the menu item.
When the user has reached the desired setting, the
PTT key is pressed to establish and confirm the
setting.
2.7.2 Power ON/OFF
Note
If a TPT unit is turned on and does not log on to
a net, the TPT is designed to turn itself off after
two minutes to conserve battery life.
The operator should connect their headset and
position their microphone directly in front of
their mouth.
To switch the power on or off, the up and down arrow keys (
i
and
j
) are used together. Press and
hold both buttons for about 1 second until the LED illuminates green. When the unit has been
powered, the operator can start a network or automatically logon to an existing network.
2.7.3 Start-Up
When a TPT unit is powered on the operator will hear a SynVoice announcement “ Channel xx,
Slave ” or “ Channel xx, Master ” indicating the current channel setting and whether the TPT unit is set
to master or slave. Pressing the menu button “ M ” will cycle through the SynVoice start-up menu
options, which are:
“ Channel xx ”
“ Master/Slave ”
“ Order Synchronize Access Point ”
