Alpine 7289M - Page 11

Refer to Figures 3 through 8 on page 5.
1.
Remove the unit from the bracket.
2. Connect the lead wires coming from the left rear of the bracket by referring to the
Connection Section, then slide the bracket into the dashboard. Bend out the tabs
along the top, bottom, and sides of the bracket to strengthen the mounting.
3. Install the metal mounting (back) strap supplied, as shown in Fig. 3. The strap can be
attached to the vehicle above or below the QRB bracket.
4. Fully insert the unit into the bracket and push the handle downward to lock the unit. To
remove the unit, raise the handle to unlock the pins, and firmly pull the unit toward
you. If the handle is not easy to raise by hand, press the Handle lever (A) (Fig. 3).
Note:
1. Secure the ground lead of the bracket to a clean metal spot using a screw (%*) already
attached to the car chassis (Fig. 4).
2. Always reinforce the installation of a removable head unit's bracket with the metal
mounting strap (Fig. 3). Otherwise, after repeated removal and insertion of the unit,
the bracket may become loose in the dashboard.
3. Before operating the unit, make sure the unit is completely inserted into the bracket
and the handle is fully down as shown in Fig. 5. This is especially necessary in the
case of excessive road vibration, rapid acceleration or vehicle collision because the unit
may come out of the bracket if it is not locked into place (Fig. 6). This could result in
personal injury to the occupants of the vehicle or physical damage to the unit.
Permanent Installation of QRB Unit
Remove the 18-pin plug assembly from the bracket. Using the 2 screws and 2 spacers
provided, connect the plug assembly directly to the unit (Fig. 7). Set the TONE BYPASS
and PRE-IN ON/OFF switches to your desired positions. Install the optional accessory kit
(Alpine 4100) as shown in Fig. 8. Use the mounting sleeve from the 4100 Kit instead of
the QRB bracket.
NOTE:
Be sure to connect the ground lead (black) to the unit chassis using the screw supplied.
