Operationandmaintechnical
parameters:
1.Introductioninthemetal
detectoroperation:
TheYM203 GRIZZLYmetal
detector iscompact,solidandeasy
touse.
Herearesomeofits
characteristics:
- EARPHONEsocket –allowsyou
toconnectheadphonestothe
equipment (notincluded)
-sounddiscrimination–the
detector will produceconstant
audiotunedetectinganonferrous
metal,anddecreasingtunewhen
detectsferrousmetal.Itworks
whenit isseton“DISC”mode.
-Pointerindicator –showsthe
possiblekindofthedetectedmetal.
-LEDlightindication–producesa
lightsignalwhenametalis
detected.
-Soundindication–produces
soundsignalofaspecificfrequency
when detectingametal.
-Waterproofsearchingcoil–gives
youthepossibilitytousethewhole
lengthofthemetaldetector for
easieroperation.
NOTE:thesearchingcoilis
waterproofbut thecontrolpanelis
not!
-Adjustablehandle–allowsyouto
adjustthelengthofthetelescope
ofthemetaldetector for easier
usage.
2.Maintechnical parameters:
-transmissionfrequency :6.99KHz
-signalfrequency:437KHz
-weight:1.8 г.
-Charging:thereisacharging

-Ifyoutestaferrousmetal,the
detectiondepth isbigger.
-Thedetectiondepth (finding
metal)isdeterminedprimlybythe
shape,sizeandqualityofthemetal
detected. Thebiggerand

PREPARATION
1. Assemblingthemetal–
detector.
Assemblingthemetaldetector is
easyandyoudonotneedany
specialskillsandtoolstodoit.Just
followthesesteps:
-connectingthesearchingcoil:
Releaseandtakeoutthenut,
tightenupthesearchingcoil,put
thehandleofthemetaldetector in
thecrampofthesearchingcoil.Put
backthescrewin theholeand
tightenupthenut.Nowthe
searchingcoilisconnectedtothe
handle.
-adjustingthelength ofthe
handle:
a)Turnthelockingnut ofthe
handleclockwiseuntil itloosens.
b)Pulltheplastichandle,thatis
belowthehandleofthemetal
detector.Prolongor shortenthe
handle,sothatwhenyoustandup
holdingtheequipment,the
searchingcoiltobe2to5cm
abovethegroundlevel,with your
handloosen.Thentightenupthe
nut of thehandle.
-connectingthecableofthe
searchingcoil:
(1)Windupthecableofthe
searchingcoilaroundthehandle.
Leavethecablelooseenough,so
youcanadjustthesearchingcoil
whenyouoperateonrough
ground.
(2)Whenyouput theplugofthe
searchingcoilin theswichofthe
controlpanel,makesureallthe
pinsoftheplugarein the
respectiveholes.

2. Chargingthebatteries:
Yourmetaldetector issupplied
with builtinbatteriesanddoesnot
needadditionalbatteries.
Ifthemetaldetector isturnedon,
turnitoff(theknobTUNEisalso
on/off button.Turnit anti–
clockwisetoturnoff the
equipment).Connectthecharging
devicejacktotheRECHARGE
socketofthemetaldetector.Then
connectthechargingdevicetothe
contact.Whenrechargesthered
light ofthechargingdeviceison.
Thechargingcontinues12to16
hours.Oncechargedthemetal
detector canfunctionupto45
hours.
Youcanprolongthetimethe
detector worksbyusing
headphones,thatneedlessenergy
thanthebuilt in speakers.
BATTERY TESTING: Whenthe
detector isturnedon,ifthebattery
statusindicator LOWBATison,if
theequipment doesnotstart,if the
soundisweakor difficulttoadjust,
rechargethebatteries.
3. Usageof theheadphones:
Youcanconnectapairof
headphones(notincludedinthe
equipment) tothemetaldetector.
Thiswayonlyyouwillhearthe
signalofthedetector.Using
headphonesalsoprolongsthelife
ofthebatteriesandmakeseasier
for youidentifyingthesoundsignal
