Mount Bracket.
Remove the clamp screw and place
the mount bracket on the handlebar near the right side of
the stem. Insert the clamp screw and tighten it until the
bracket does not move when the Altimeter is inserted or
removed. Small diameter handlebars may require taping
beneath the clamp for a tight fit.

Altimeter 50 Installation.
Slide the Altimeter into
the mount bracket from front to rear until it snaps on.
Advance the Altimeter to the speed function. Spin the
front wheel and watch for a speed reading. If the display
remains at zero, check the wire connection plugs at the
receiver, and make sure that the receiver and transmitter
are aligned and nearly touching.

Receiver Wire.
Secure the wire with ties or tape
starting at the receiver. Attach the wire only to parts that
rotate when the bicycle is steered–the fork, the handlebar
stem, or the front brake cable. Do not attach the wire to
the head tube. Wrap excess wire around the front brake
cable housing.

Batteries.
Install the batteries in their compartments
on the back of the Altimeter with their positive (+) sides
toward the caps. Press in the caps with your thumb. To
remove the batteries, pry the caps up with a screwdriver.
Note: Removing the batteries erases setup data. After
installing batteries complete the setup procedure. Warn-
ing: Use only Altimeter 50 batteries–see specifications.
