The JWAT410 series waterproof phone case is made of aluminum alloy die-casting, which has good impact
resistance and protection performance. The high-temperature powder on the surface is not electrostatically
sprayed to prevent static electricity. The circuit board adopts the concept of integrated design, and integrates the
basic call circuit and noise removal circuit in a machine. And preferably foreign well-known brand components.
After high and low temperature testing, procurement and production, the circuit undergoes strict protection
treatment, so that the environmental adaptability of the whole machine is further improved. The phone adopts an
anti-noise handle, and the built-in circuit of the phone has strong anti-interference ability, and the call sound
quality is stable and clear.

1.2.2 Relative Humidity：≤95％（ room temperature）
1.2.3 Atmospheric Pressure：80～110KPa
2. Product Structure Characteristics
2.1 The hands-free waterproof telephone is composed of two parts: a shell (including a die-cast aluminum
shell and a cold-rolled steel panel) and a double-sided integrated circuit motherboard.

is the ground wire, which must be effectively grounded during installation, and the brown-blue is the zero live
wire, which is connected to the AC220V AC power supply through the terminal block in the waterproof junction
box. Note When wiring, no copper wire should be exposed, and the terminal screw must be locked tightly and
not locked to the insulated wire.
