Whether at home or in the office,  your CORE-S4 connects to your WiFi network (802.11 b/g/n 2.4Ghz), saving you from using your data plan. And because of its KaiOS operating system, many of the most popular apps are installed by default on your CORE-S4. This means you can access Facebook and WhatsApp as soon as you start your phone…

Designed with CROSSCALL’s values firmly in mind, the CORE-S4 embodies the brand’s commitment to durability, and to building a mobile phone you can rely on over time,
without limiting its usability. It has a long battery life, thanks to its 2300 mAh battery, it can withstand impacts and drops, and is resistant to fresh water, salt water, chlorinated water, dust and other microparticles. Durability, reliability and repairability are its key qualities.

Its bright screen and one-piece backlit keypad make it easy to use, even when wearing gloves. The 100 dB speaker means you can make clear and audible calls in noisy places, even when hands-free, and the powerful torch will help you find your way in low-light areas. Its compatibility with X-LINK TM technology puts the CORE-S4 at the heart of an accessory ecosystem designed to simplify your everyday life.

Tips and precautions for charging your battery

1. Open the dust cap and connect the cable and AC adapter supplied in your pack using the USB-A port. Then plug the other end of the cable into the micro USB port on your phone.
2. Plug the AC adapter into an electrical outlet.
3. When the battery is fully charged, unplug the phone from the charger. First, unplug the charger from the device, then unplug it from the electrical outlet.

Never charge your phone using the X-LINK TM* magnetic connection and the USB connection together, as this could shorten the lifespan of your phone’s equipment.

The battery is built into the phone and is not removable. Do not remove the battery yourself.

• To avoid prematurely draining the device’s battery, we recommend that you follow the battery charging instructions for each charging cycle. To do this, it is better to top  up the battery when it reaches 20% and avoid charging it beyond 80%, rather than topping it all the way up to 100% from zero.
• Only use approved chargers and cables that are compatible with your phone. Using unapproved chargers or cables may cause the battery to explode or damage the phone.
• Avoid using your phone while it is charging. Do not cover your phone or the power adapter.
• Connecting the charger incorrectly could seriously damage your phone. Any damage caused by misuse is not covered by the warranty.
• Remove the charger from the electrical outlet when the phone is not charging.
• The phone may not switch on straight away if you are charging a drained battery. Once the phone has been charging for a while, the phone will start normally
• If the AC power is lower, your phone may take longer to charge
• If you use unconventional chargers such as computers, the charging time may be longer
• The charging time may vary depending on the ambient temperature and the remaining battery leve
• The phone can be safely charged at a temperature between 0°C and 40°C. Charging at temperatures below 0°C or above 40°C may compromise battery performance and shorten battery life. Prolonged charging at extreme temperatures will damage the battery
• While charging, the phone and charger may become hot, this is quite normal and should not affect the performance or lifespan of your phone. If the battery seems hotter than usual, stop charging it. Put your phone in a cool place and leave it to cool. Avoid prolonged contact with the surface of your phone when it is hot.

Emergency calls
In the event of an emergency, if the phone is switched on and you are in the network coverage area, it can be used to make an emergency call. However, emergency numbers may not be accessible on all networks. You should never rely on your phone to make emergency calls.
Recommendations to reduce the user’s exposure to radiation

• Use your mobile phone in areas covered by your network to reduce the amount of radiation received (especially in underground car parks or when traveling by train and by car).
• Use your phone when there is good reception (i.e. maximum number of bars for the network)
• Use a hands-free kit.
• During calls, keep the phone away from the tummy of pregnant women and the lower abdomen of teenagers
• Children and teenagers should make reasonable use of mobile phones by avoiding, for example, night-time calls and limiting the frequency and duration of calls.
