I would ;like better instructions – and a set for each model – As I give these as gifts to some who are not car/electrically literate – I make up single side A4 instruction for each model and put in poly-pocket in box – eg:
GOOLOO GT1500 JUMP STARTER GREEN –WITH BOOST OVERRIDE
Charge fully before use and then every 2/3 months -mains charger or a car charger
PROCEED WITH CAUTION – Remember the Joiner – Measure TWICE – CUT ONCE!
– CHECK CONNECTIONS BEFORE TURNING ONN
1. Connect RED CLAMP to POSITIVE BATTERY TERMINAL and BLACK CLAMP to NEGATIVE BATTERY TERMINAL. Turn ON- best if unit has 2 Bars of power – but always try!
CHECK the indication lights on the Jump Cable.
READY =SOLID GREEN LIGHT
RED LIGHT AND BLEEPING = WRONG POLARITY –
check Red Jump Lead connected to (+) of battery
NO LIGHTS, NO BEEPING = Battery Completely Flat or damaged – try BOOST FUNCTION – see 3 below
2. Start Car within 30 seconds
3. If car battery is very low – NO LIGHTS on Jump Cable – DOUBLE CHECK RED JUMP LEAD TO (+)
Hold Down BOOST button on side of Jumper Cable – to force Output – without protection SOLID GREEN LIGHT comes on.
BOOST Override – DISABLES SAFETY NO Reverse Polarity and Short Circuit and O/L PROTECTION -MAKE SURE ALL CONNECTIONS CORRECT BEFORE USING!
Torch activated by turning ON unit –Then Holding Power button down for a further 2-3 seconds Light comes on – push gently go to STROBE and again for SOS and OFF.
