Wireless
INTRODUCTION
Thank you for purchasing a Nashbar
computer. With all the features that a professional
rider needs to keep track of a ride, the Nashbar
Tempo Wireless is the perfect accessory for any
cyclist. The convenience of coded wireless
transmission makes installation simple and
virtually eliminates interference issues.
BATTERY INSTALLATION
To help you get started quickly, the computer
and transmitter batteries have been installed
at the factory. Under normal use the batteries
should last one to two years. The Nashbar
Tempo Wireless uses a 3V CR2032 button
cell battery (available at most drug stores or
electronic shops) in both the computer and
the transmitter.
NOTE: Most problems that occur with cycle
computers are caused by weak or dead
batteries. Should you need to replace the
batteries, follow the steps below.
COMPUTER HEAD
NOTE: During a battery change, all data will
be cleared from memory. Make a note of your
current wheel size settings and cumulative
odometer mileage before replacing the battery
so you can reprogram these values once the
battery is replaced.
STEP 1: Remove the
battery cover from the
underside of the computer
using a coin (Fig. 1).
Remove the old battery
and dispose of it properly.
STEP 2: Install a fresh
battery with the positive
(+) side facing the battery cover.
STEP 3: Install the battery cover securely,
making sure the rubber O-ring seal around
the battery compartment is still in place and
seated properly.

Wireless computer includes two wheel size
settings ( and
on two bikes with different wheel sizes (e.g.
your road bike and mountain bike).
TEMPERATURE
Displays air temperature in °F or °C, from
32°F to 122°F.
AUTO SLEEP
To prolong battery life, the Nashbar Tempo
Wireless automatically enters "sleep" mode
after 30 minutes of inactivity. In sleep mode,
only the time of day will be displayed. To
activate the computer when it's in sleep
mode, simply press the MODE button.
DETERMINE WHEEL SIZE
The Nashbar Tempo Wireless uses wheel
circumference (measured in millimeters)
to calculate speed and distance. Before
Fig 1
programming the computer, calculate
wheel circumference using one of the three
methods below.
1. Select size from chart (least accurate):
Use the chart below to find the
circumference for your tire size. The chart
lists the programming sizes for some of
the most popular tire sizes currently in use.
These numbers are estimations which may
not precisely match the circumference of
your wheel, due to variations in tire size
between brands and models.

Measure your wheel diameter (including
wheel and tire) in millimeters (1 inch =
2026
25.4mm) and multiply by 3.1416. This value

is your wheel circumference.
