• Hali ya saa ya saa: For timing events, including lap/split functions.
• Humidity/Temperature/Heat Index Mode: Shows environmental readings.
• Hali ya Kengele: For setting and activating the programmable alarm.

6.2. Kuweka Saa na Tarehe

1. Katika Hali ya Muda, bonyeza na ushikilie MODE kitufe hadi tarakimu za wakati zianze kumweka.
2. Tumia ANZA/ACHA kitufe cha kurekebisha tarakimu inayomweka (saa, dakika, sekunde).
3. Bonyeza kwa LAP/SPLIT/RESET button to move to the next digit or setting (e.g., 12/24-hour format, date).
4. Mara tu mipangilio yote ikiwa imewekwa, bonyeza kitufe cha MODE button to exit setup.

6.3. Using the Stopwatch Functions

1. Badilisha hadi Hali ya Kisimamishaji kwa kutumia MODE kitufe.
2. Bonyeza ANZA/ACHA kuanza kuweka muda.
3. Bonyeza LAP/SPLIT/RESET to record a lap or split time. The display will momentarily show the recorded time while the stopwatch continues to run in the background.
4. Bonyeza ANZA/ACHA tena kusitisha saa ya kupimia.
5. Ili kuendelea, bonyeza ANZA/ACHA. Ili kuweka upya, bonyeza LAP/SPLIT/RESET wakati saa ya kupimia imesitishwa.
6. To recall stored lap/split times, press the KUMBUKA button in Stopwatch Mode. Use LAP/SPLIT/RESET to scroll through memory.

6.4. Humidity, Temperature, and Heat Index Measurement

The HW30 automatically measures and displays humidity, temperature, and calculates the heat index in the dedicated mode.

1. Switch to Humidity/Temperature/Heat Index Mode using the MODE kitufe.
2. The display will show the current humidity percentage, temperature (in °F or °C), and the calculated heat index.
3. Allow a few minutes for the sensors to stabilize and provide accurate readings, especially when moving the device between environments with different conditions.

6.5. Kuweka Kengele

1. Badilisha hadi Hali ya Kengele kwa kutumia MODE kitufe.
2. Bonyeza na ushikilie MODE kitufe hadi tarakimu za muda wa kengele zianze kuwaka.
3. Tumia ANZA/ACHA button to adjust the flashing digit (hours, minutes).
4. Bonyeza kwa LAP/SPLIT/RESET button to move between hours and minutes.
5. Mara tu muda unaotaka wa kengele utakapowekwa, bonyeza kitufe cha MODE kitufe cha kuthibitisha.
6. Ili kuamsha au kuzima kengele, bonyeza ANZA/ACHA button in Alarm Mode. An alarm icon will appear on the display when activated.
