InvoTek BlueTalk User Manual

BlueTalk User Manual

Thank you for purchasing BlueTalk! BlueTalk is a Bluetooth hub which,
when paired with InvoTek’s MultiAccess Android app, enables the user
to control up to two personal electronic devices via one input device.
The Android input device runs InvoTek’s MultiAccess Android app. This
app provides an on-screen keyboard and cursor control and enables
the user to select which connected device to control. When the user
makes a keyboard selection or cursor movement in MultiAccess, the
command is sent via Bluetooth to the selected device through
BlueTalk. To the connected devices, BlueTalk looks like a normal
Bluetooth keyboard and/or mouse. In addition,
BlueTalk displays text from MultiAccess on a
forward-facing LCD and plays text-to-speech
through the built-in speakers.

Input Switches

There are two switch jacks and buttons labeled SW1 and SW2. Users
can connect input switches here to perform switch scanning within the
MultiAccess app. MultiAccess provides sophisticated settings to
improve switch access for a user. BlueTalk accepts any 3.5mm mono
switch output, such as a push-button switch or the output of a Sip-and­Puff switch. The small buttons beside each switch jack are there for
convenience to test the functionality of switches during setup –
pressing a button is identical to activating its associated switch.

Relay Output

The jack labeled “Relay” allows the user to connect wired devices such
as a nurse call button. The relay is activated through the MultiAccess
app. The relay supports a maximum of 1 amp of current and 30 volts
DC. Exceeding these specifications may damage BlueTalk.

Audio Jack

The jack labeled “Audio” is a 3.5mm headphone jack. When
headphones are connected, all audio is routed to the headphones
instead of through the built-in speakers. By using headphones,
communication between partners can become more private.

Charging Port

The Micro-B USB jack labeled “CHG” is used to charge the device.
When the provided USB cable is connected and powered, the device
will charge. On the front of BlueTalk is a battery symbol with four LEDs
that display the current battery status. When the device is charging,
the battery LED corresponding to the charge level will blink.

On/Off Switch
The switch labeled “ON” is the on/off switch. To turn the device on,
slide the switch upward.

Vol+/Vol- Buttons

These buttons control the volume of the built-in speakers and
headphones when connected. The current volume setting is displayed
on the LCD when a button is pressed.

Contrast

The “Contrast” knob adjusts the contrast of the front LCD panel.

Unpair Button

This button is used to disconnect BlueTalk from all Bluetooth devices.
This includes forgetting all the devices which BlueTalk attempts to
reconnect to on power up. To do so, hold down the Unpair button for
three seconds until a long beep is heard.
