※ Due to the function displaying the b est lap time and average lap time, it ta kes at least
three units of memory to store 1 time data. If you store data only in one channel, you can
use 300 units of me mory per channel. If you use more than one channel, the units of
memory you can use will be less than 300 units of memory in total. For example, if the
measured time data are stored in one channel, 30 0 units of memor y can be used , but if
data is divided and stored in 2 channels , 297 units of memory can be used in total.
※ When only one channel (CH) is used, the units from L-1 to L-300 are memo rized.
Although the units after L-301 are also measured, they are not memorized.
※ When the memory is full, the data for the oldest channel is deleted in channel
increments to register new memory data.

■ REMARKS ON THE BATTERY
● Band
The band touches the skin directly and becomes dirty with sweat or dust. Therefore, lack of care may accelerate deterioration
of the band or cause skin irritation or stain on the sleeve edge. The watch requires a lot of attention for long usage.
Metallic band
・Moisture, sweat or soil will cause rust even on a stainless steel band if they are left for a long time.
・Lack of care may cause a yellowish or gold stain on the lower sleeve edge of shirts.
・Wipe off moisture, sweat or soil with a soft cloth as soon as possible.
・
To clean the soil around the joint gaps of the band, wipe it out in water and then brush it off with a soft toothbrush.
（Protect the watch body from water splashes by wrapping it up in plastic wrap etc.）
・
Because some titan bracelets use pins made of stainless steel, which has outstanding strength, rust may form in the stainless steel parts.
・ If rust advances, pins may poke out or drop out, and the watch case may fall off the bracelet, or the clasp may not open.
・ If a pin is poking out, personal injury may result. In such a case, refrain from using the watch and request repair.
Leather band
・
A leather band is susceptible to discoloration and deterioration from moisture, sweat and direct sunlight.
・ Wipe off moisture and sweat as soon as possible by gently blotting them up with a dry cloth.
・Do not expose the watch to direct sunlight for a long time.
・Please take care when wearing a watch with light-colored band, as dirt is likely to show up.
・
Refrain from wearing a leather band watch other than Aqua Free bands while bathing, swimming, and when
working with water even if the watch itself is water-resistant enforced for daily use（10-BAR water resistant）.
Polyurethane band
・
A polyurethane band is susceptible to discoloration from light, and may be deteriorated by solvent or atmospheric humidity.
・ Especially a translucent, white, or pale colored band easily adsorbs other colors, resulting in color smears or discoloration.
・Wash out dirt in water and clean it off with a dry cloth.
（Protect the watch body from water splashes by wrapping it up in plastic wrap etc.）
・ When the band becomes less flexible, have the band replaced with a new one. If you continue to
use the band as it is, the band may develop cracks or become brittle over time.
Silicone band
・ As for material characteristics, the band is easily dirtied, and may be stained and discolored. Wipe
off dirt with a wet cloth or cleaning tissue.
・ Unlike bands of other materials, cracks may result in the band being cut. Take care not to damage
the band with an edged tool.
Notes on skin irritation and allergy
Skin irritation caused by a band has various reasons such as allergy to metals or leathers, or skin
reactions against friction on dust or the band itself.
Notes on the length of the band
Adjust the band to allow a little clearance with your wrist to ensure proper airflow.
When wearing the watch, leave enough room to insert a finger between the band and your wrist.
● Inspection and adjustment by disassembly and cleaning (overhaul)
・
Periodic inspection and adjustment by disassembly and cleaning (overhaul) are recommended approximately
once every 3 to 4 years in order to maintain optimal performance of the watch for a long time.
・According to use conditions, the digital display may go out due to liquid leakage.
・
As the parts such as the gasket may deteriorate, water-resistant performance may be impaired due to intrusion of perspiration and moisture.
Please contact the retailer from whom the watch was purchased for inspection and adjustment by disassembly and cleaning
(overhaul). For replacement of parts, please specify “SEIKO GENUINE PARTS.” When asking for inspection and adjustment
by disassembly and cleaning (overhaul), make sure that the gasket and push pin are also replaced with new ones.
・ When your watch is inspected and adjusted by disassembly and cleaning (overhauled), the movement of your watch may be replaced.
