BSZ2010 proof wall clock, quartz BSZ2010 Changzhou bsz2010 explosion-proof quartz, BSZ2010 proof quartz watch, BSZ2010 bell proof, explosion-proof digital clock, electronic clock explosion, explosion-proof digital clocks, quartz clocks Shanghai explosion: The product has explosion-proof certification, inspection reports! Name: Ex Quartz Model: BSZ2010 voltage: DC1.5V Ambient temperature: -15 ~ + 50 ℃ (indoor) Relative humidity: ≤85% Atmospheric pressure: 80 ~ 110 kPa proof mark: ExibⅡCT6 Operating voltage: DC1.25 ~ 1.70V ( a 5 # battery) Dimensions (mm): Square: 300 * 300 * 150 GW: 5.25kg (net weight) to use explosion-proof quartz install the battery: Open the battery compartment, according to the battery box indicates the "+", "-" polarity markings into the battery, second hand begins to run, showing proof bell is working. When the dial is aimed at: the back of the movement of the setting wheel along appropriated to standard time. Note that quartz is intrinsically safe explosion proof products, change any components in the circuit can affect the performance of explosion-proof quartz, so do not require the user to disassemble any electronic components inside the movement. Explosion clock power supply circuit is equipped with safety protection devices, replacing the battery will not affect the performance of explosion-proof quartz clock.
