The TZ900 is a Bluetooth 3.0 Car Kit designed for sunvisor mounting, offering hands-free communication and music streaming in a vehicle.

The device serves as a car kit, enabling users to make and receive calls, and stream music from their phone via Bluetooth. It features several buttons for various functions:

On/Off button (1): Powers the device on or off.
Private talking button (2): Allows the user to switch to private talking mode during a call. In standby mode, pressing this button activates voice dialing.
Play/pause phone music button (3): Used to stream music from a connected phone. Pressing it once starts music playback, and pressing it again pauses it.
Answer the call button (4): Used to answer incoming calls. A double-click on this button redials the last phone number.
Hang up/reject the call button (5): Used to end an ongoing call or reject an incoming call. Long pressing this button rejects a call.
Volume +/- button (6): Adjusts the volume. When playing music, a long press on the '+' button controls music playback (likely fast forward or next track, though the manual specifies "music playback" for '+', and "play the next song" for '-').

Bluetooth Pairing:

Phone 1 Connection: To connect the first phone, users need to enable Bluetooth on their phone, search for "TZ900" in the list of available devices, and select it. The pairing password is "0000".

Then, search for "TZ900" on the second phone and enter the password "0000". After this, pressing the off button (1) completes the process.
