SET/EL (Top Left): Used to enter setting modes and activate the electroluminescent backlight.
MODE (Bottom Left): Cycles through different watch modes (Time, Chronograph, Alarm).
START/PAUSE (Top Right): Used to start/stop functions in chronograph mode and adjust values in setting modes.
ADJ (Bottom Right): Used to adjust values in setting modes and reset functions.

Setup: Setting Time and Date

Follow these steps to set the time and date on your watch:

From the normal time display, press the MODE button repeatedly until the seconds begin to flash. This indicates you are in time setting mode.
Press the ADJ button to reset the seconds to zero. If the seconds are reset when the value is between 30 and 59, the minutes will advance by one. If reset when between 00 and 29, the minutes remain unchanged.
Press the START/PAUSE button to move the flashing selection to the minutes.
Press the ADJ button to adjust the minutes.
Press the START/PAUSE button to move the flashing selection to the hour.
Press the ADJ button to adjust the hour. Note the 'A' or 'P' indicator for AM/PM, or 'H' for 24-hour (military) format.
Continue pressing START/PAUSE to cycle through setting the year, month, and day. Use the ADJ button to change the values for each.
Once all settings are correct, press the MODE button to exit the setting mode and return to the normal time display.

Tip: It is recommended to keep these instructions handy for future adjustments, as the setting process can be intricate.

Maintenance

Water Resistance

Your Armitron Sport watch is water resistant to 165 feet (50 meters). This means it is suitable for short periods of recreational swimming, but not for diving or snorkeling. Avoid pressing buttons underwater, as this can compromise the water resistance.

Battery Replacement

The watch uses 1 Lithium Metal battery (included). When the display becomes dim or functions become erratic, the battery may need replacement. Battery replacement should ideally be performed by a qualified watch technician to ensure proper sealing and maintain water resistance.

Cleaning

Clean your watch with a soft, damp cloth. Avoid using harsh chemicals or abrasive materials, which can damage the case or strap.

Troubleshooting

Problem	Possible Cause / Solution
Display is dim or difficult to read.	The watch features a reverse LCD display, which can appear dimmer in certain lighting conditions. Ensure you are viewing the display at an optimal angle. Press the SET/EL button to activate the backlight for improved visibility in low light. Battery may be low. Consider professional battery replacement.
Difficulty setting time/date.	Refer to the "Setup: Setting Time and Date" section carefully. The sequence of button presses is specific. Ensure you are in the correct setting mode (seconds flashing). Be mindful of the seconds reset function and its effect on minutes.
Watch is not functioning.	The battery may be depleted. Seek professional battery replacement. If the watch has been exposed to water beyond its resistance rating, internal damage may have occurred.
