SPA Spectrum Analyzer 

internal battery

The internal battery is a high capacity Lithium-ion polymer 1000mAh. This is the same battery technology 
used in cell phones and modern laptops and tablet computers. 

The power switch is a 

true hard switch

 connecting the battery in ON position, fully isolating the battery in the 

OFF position. As the battery is fully disconnected in the OFF position, you can keep your RF 

Spectrum 

analyzer

 stored for months and the battery will keep the charge intact, as opposed to cell phones or laptops 

which typically implement a 

soft switch

 which slowly discharge the battery by drawing a microamperes 

continuously from it. This doesn't happen in your 

LATNEX hand-held RF analyzer device

Note there is actually a self-discharge effect in the battery but it is so negligible that you can store your 
device for a year or more and a battery will not be depleted. 

Charging the internal battery 

To charge the internal battery, plug it in to a powered USB port or USB wall-wart charger via the USB mini 
socket. For the internal charger to access the battery, you must set the power switch to ON position, 
otherwise the device will be running from USB but will not use or charge the internal battery. 

The RF signal analyzer 

may draw up to 500mA according to USB standard, and may take up to 3hs max to 

charge a fully discharged battery in normal conditions. We recommend the first time to be charged for up to 
8hs. 

IMPORTANT 

Never charge your device unattended or in any place where there is a risk of fire. 

Never store 

the SPA Spectrum Analyzer

 in a place where temperature may go

 

beyond 50ºC (122F). 

A car can heat up incredibly quickly in the 

sun

, especially in the summer, and 

damage or reduce the lifetime of your battery if stored in such an environment. 

If your battery doesn't seem to hold a charge or work properly, or if the unit gets 

hot when charging, switch the power button OFF immediately and review and/or 

replace your battery. 

Never use 

any of the LATNEX Spectrum Analyzer

 

models 

with a damaged battery or 

with a Lithium Ion battery different than the one officially supplied by technical 

service, which includes a 

protection circuit for safety. Contact 

EMR Shielding Solutions

 

if you have any 

question on

 

any matter related with your battery or if you need a replacement.
