Giant Revive DX Computer User Guide
A. Physical Descriptions
1. Mode Button (on front of computer)
2. Set Button (on rear left when looking at rear of computer) 3. ½ Button (on rear right when looking at rear of computer)
A. To remove the cycle computer from the handlebar, first loosen the anti-theft screw (on rear of computer) and then turn the knob.
B. Putting the computer back on the handlebar is the reverse operation.
B. Battery Change
Low Battery Indicator
1. The low battery symbol will appear on the display to indicate the battery is nearly exhausted.
2. Replace battery with a new one within a few days after the symbol has appeared. Otherwise the stored data may be lost when the battery voltage is too low.
Battery Change
1. All data will be cleared when battery is replaced.
2. This computer allows you to re-key in data for ODO1, ODO2 and T-TM from previous use after replacing the battery.
3. Keep a record of previous data for ODO1, ODO2 and T-TM before removing the battery.
4. Replace with a new LR44 (cross reference type a76, AG13 or V13GA) battery in the compartment on the back of the computer with the positive (+) pole toward the battery cap.
5. Initiate the main unit again.
C. Main Unit Setup (All Clear)
Initiate the Computer
1. A battery is already loaded in the main unit when purchased.
2. Hold down the Mode button and the ½ button simultaneously for more than 3 seconds to initiate the computer and clear all data. Important: Be sure to initiate the computer before it is used, otherwise it may run errors.
3. The LCD segments will be tested automatically after the unit is initiated. 4. Press Mode button to stop LCD test.
Unit Selection Press Mode button to choose Km/h or Mile/h. Then press the Set button to store selection.
ODO1, ODO2 and T-TM Data Setting
1. This function is designed to re-key in former data of ODO1, ODO2 and T-TM when battery is replaced.
2. A new user does not need to set this data. Each press of the Set button skips one setting data process.
3. Data Setting Process
a. The data is adjusted for each digit separately. The setting digit is flickering.
b. Quickly press the Mode button to increase the digit value by 1.
c. To change the setting digit hold down the Mode button for more than 2 seconds.
d. Press the Set button to store the data then change to the next setting or the normal operation.
Wheel Circumference
1. Roll the wheel until the valve stem is at its lowest point, closest to the ground, then mark this first point on the ground.
2. Get on the bike and have a helper push you forward until the valve stem returns to its lowest point. Mark the second point on the ground. (Sitting on the bike achieves a more accurate reading since the weight of the rider slightly changes the wheel circumference).
3. Measure the distance between the marks in millimeters. Enter this value to set the wheel circumference. Option: wheel circumference default setting = 1564.
4. Unit will change to the normal operation after the circumference setting.
D. Functions
SPD: Current Speed The current speed is always displayed on the upper set when riding.
ODO1, ODO2: Bike1 odometer, Bike2 Odometer
1. The odometer accumulates the total distance as long as the bike is running.
2. The computer design has 2 wheel circumference memories to calculate data for 2 bikes. The odometer is separated for each bike.
3. It displays one ODO data only when the bike is selected in the current status.
T-TM: Total Riding Time The T-Tm accumulates total riding time while riding in Bike1 or Bike2.
T-ODO: Total Odometer The T-ODO is the sum of ODO1 plus ODO2.
12HR or 24HR Clock
Time can be displayed in either 12HR or 24HR format.
AVG: Average Speed
1. Average speed is calculated from the DST divided by the TM. The Average data counted is from the last reset to the current point.
2. It will display 0.0 when TM is less than 4 seconds.
3. It is updated about every second when TM is over 4 seconds.
4. It displays an “Err” symbol when either the TM is over 100 hours or the DST is over 1,000 km (or miles). Reset the unit in order to restart.
DST: Trip Distance The DST function accumulates the distance data from the last reset operation as long as the bike is being ridden.
TM: Riding Time
1. The TM totals the riding time from the last reset operation.
2. It will automatically begin counting upon riding, and continue to count 3.2 seconds to confirm that no more wheel sensing signal is sent when riding is stopped. But this computer revises back the over-counted 3.2 seconds automatically.
3. It displays in 0.1 second increments when TM is less than 1 hour and changes to 1 second increments after 1 hour. It will restart from zero after 100 hours.
