The new phone is equipped with a vibration function that vibrates 1.4 times more than previous models. The vibration is clear, making it easier to notice incoming calls.
The system will periodically notify you of unconfirmed missed calls with a sound or vibration. This will prevent you from forgetting to answer the call. (Snooze interval: 5, 10, 20, 60 minutes after the call)
If you miss two or more calls from the same person within 10 minutes, the ringtone will gradually get louder and the vibration will last longer to make the call easier to notice.
Equipped with a large receiver *1, you can hear the sound clearly even when talking in a crowd or when the other person's voice is quiet. In addition, the area of the receiver hole from which the sound comes out has been expanded to about 1.5 times *2 that of our previous model. You can talk without worrying about where you place the earphone against your ear.
You can change the sound quality of the other person's voice from the standard to two different sound qualities that are easier for you to hear.
The design is easy to use, with a rounded shape that fits comfortably in the hand and easy-to-press keys. The metallic exterior also adds a touch of quality.
The USB Type-C plug is symmetrical and, unlike conventional external plugs, can be inserted in either direction, making charging easy.
It is equipped with a "large-capacity 1,700mAh battery" and a "battery saver" function that reduces power consumption.*2 It can be used for a long time, so it is safe for business trips and travels.
In addition to being shock resistant, it also meets MIL standards (MIL-STD-810G) for being waterproof (immersion), vibration resistant, high temperature storage (fixed), high temperature storage (variable), high temperature operation (fixed), high temperature operation (variable), low temperature storage, temperature shock, and low pressure storage, allowing it to be used in a variety of environments.
The waterproof design means you can answer calls immediately even while cooking or taking a bath, and it can also be washed with water. It is also dustproof, so you can use it without worrying about dust and dirt.
It has passed the wipe test *, so if it gets dirty, you can just wipe it with a disinfectant sheet and use it as is. Even if it gets dirty, you can just wipe it clean and use it again, so it's hygienic.
Charging for a long time puts a strain on the battery and it tends to deteriorate. This charging setting limits the battery to 85% of its maximum capacity. This reduces the strain on the battery and makes it last longer.
By connecting to your home Wi-Fi, you can watch videos and other large-volume content without worrying about data usage. *2 You can also connect your laptop or tablet to the Internet while on the go, just like a mobile Wi-Fi router. *1
In addition to walking, it can also calculate steps and calories burned while jogging, cycling, etc.
You can receive OneSeg broadcasts and FM radio broadcasts *.
When changing models, etc., you can use a microSDTM memory card* to transfer call audio data recorded/saved inside the device to your new model.
[About MIL-STD-810G] Tests conforming to the 10 items of the US Department of Defense procurement standard (MIL-STD-810G) (shock resistance: test in which the product is dropped from a height of 1.22m onto plywood (lauan wood) in 26 directions, waterproofing (immersion): test in which the product is immersed in water at a depth of about 1.5m for 30 minutes, vibration resistance: vibration test for 3 hours (1 hour each in 3 directions / 20 to 2,000Hz), high temperature storage (fixed): high temperature durability test for 4 consecutive hours at 60℃, high temperature storage ( We conduct the following tests: high temperature durability test: high temperature operation (fixed): operation test at 50°C for 3 consecutive hours, high temperature operation (variable): operation test with temperature change in 3 cycles from 32 to 49°C, low temperature storage: low temperature durability test at -30°C for 4 consecutive hours, temperature shock: temperature durability test with rapid temperature change from -21 to 50°C for 3 consecutive hours, low pressure storage: low pressure storage test for 2 consecutive hours (57.2kPa/equivalent to an altitude of approximately 4,572m).
[About waterproofing] IPX5 means that the phone will maintain its functionality even when sprayed with water from a nozzle with an inner diameter of 6.3 mm from any direction, with water at a rate of 12.5 L per minute from a distance of about 3 m for more than 3 minutes. IPX8 means that the phone will not get wet and will maintain its functionality even if it is gently submerged in a tank of tap water at room temperature and still water at a depth of 1.5 m and left at the bottom for about 30 minutes. Do not pour or immerse the phone in anything other than tap water, such as soap, detergent, seasonings, juice, or seawater. Also, do not immerse or pour hot or cold water on the phone.
[Dust resistance] IP5X means that the phone can be placed in a device filled with dust particles with a diameter of 75 μm or less for 8 hours, agitated, and then taken out of the device, still functioning as a phone and remaining safe. Do not place the phone on sand, etc.

This product has been designed to comply with the technical standards *1 set by the government regarding the human absorption of radio waves, as well as the radio wave protection limits recommended by equivalent international guidelines. These international guidelines were established by the International Commission on Non-Ionizing Radiation Protection (ICNIRP), which is in collaboration with the World Health Organization (WHO), and the limits include a sufficient safety margin for all users, regardless of their age or health condition.
National technical standards and international guidelines define the permissible value for radio wave protection as the Specific Absorption Rate (SAR), which represents the average amount of radio wave energy absorbed by the human body, and the permissible SAR value for mobile phones is 2.0 W/kg.
The maximum SAR value for this product [DIGNO® Keitai 3 903KC] at the side of the head is 0.675W/kg, and the maximum SAR value when worn on the body *2 is 0.530W/kg. Although there may be slight differences in SAR depending on the individual product, all of them meet the allowable value. Mobile phones are designed to have the minimum transmission power required for communication with mobile phone base stations, so when actually making a call, the SAR value is usually smaller. In general, the closer the distance from the base station, the lower the output of the mobile phone.
The World Health Organization has stated that "Numerous studies have been conducted over the past 20 years to assess whether mobile phones pose a potential health risk. To date, no adverse health effects have been established as being caused by mobile phone use."
