Push buttons are for use on broadcast receptlon The broadcast cllal scale reads from
left to right 1750 to 550 kllocycles The automatlc buttons are similarly dlsposed ln se
quence from left to rxght so that any partlcular button may be set to a desrred station
wnthm 1ts range Two buttons may even be set to the same statron xi des1red Thls per
mlts settmg to drfferent programs vthlch are very close together on the dual scale Do not
press two buttons ln at one time If thxs IS done by mlstake move manual lever to manual
tunmg as shown by dial hght Thxs releases both buttons
Pre settmg For Desxred Stations
Determme which broadcastmg statxons you favor for automatxc tuning and set the but
tons to the programs commg from the ones you re ularly 11sten to To do thms first turn
set on and tune m one program manually to desired volume In tunmg, observe electrxc
eye which shows 1ts narrowest shadow when rece1ver zs correctly tuned Program should
be lxstened to several mmutes after fxrst turmng set on 1n order that the tubes may warm
up fully before the automatxc buttons are pre set For the Hrst push button at left begm
uxth a desired statlon near left of scale m range 1750 to 1400 kxlocycles
At the rear of cabmet there is a selector dxsc whxch has two rings each carrylng con
tactors correspondmg to the push buttons Remove protective cover to expose thxs dlsc
wxth nts rmgs to vxew when pre settxngs are made The selector d1SC comprxses two sectors
separated by a vxsxble and narrow msulated gap When the lower gap registers wxth a par
t1cular contactor carrred by emther of the two rxngs the push button connected to that con
tactor controls the gnven statron settmg Use the contactor whxch IS nearest to the insulated
lower gap on disc Loosen :ts support screw just enough so that thxs contactor can slide on
its rmg support and move the contactor so that its ball poxnt rests on this gap Then
curacy of pre settmg move the front lever to electric tunmg posxtlon as shown by dial
lrght mdrcator Press m the first button at left the one now pre set If correct the selected
program wxll be heard If not repeat pre setting operatlon just dxscussed movlng the cor
rect contactor to posmon at the lower dlsc gap Once set do not move thus contactor
For mdexmg other statxons proceed srmrlarly wxth the next push button and xts corre
spondmg control contactor and so on untnl all deslred buttons are pre set to the partncular
stations wanted To change select1on at some later trme repeat the procedure for a partxcu
lar button but leave the pre set buttons held securely by support screws before replacmg
proteetxve cover over rear drsc Exact pre settmgs may be had by carefully mos mg the
contactor connected to each push button and slxghtly shlftxng 1f5< posrtlon if requxred to regrster
with lower dxsc gap for the desxred statxon Settmgs may be made as desxred and lf you
wish all or more programs m one range ask for spec1al mstructxons It rs recommended
that the servrce man who mstalls your radxo set up the statlons you want on your push
buttons Mark each push button wxth proper call letter tab furmshed as dxrected at top ol
tab sheet Once pre set you may leave lever m electric tunmg posltlon for all broadcast
tunmg either manually or automaucally
NOTE For recexvers equlpped wrth automatlc frequency control Most exact pre set
tmgs may be made when lever IS ln manual posxtxon without thls control D0 not pre set
to a weak statxon very close on dlal scale to a powerful station as the control wxll pull 1n
the strong statxon when too close Use your manual control for weak dlstant stations com
monly subject to fadmg 1n and fadxng out of volume as well for short wave recept1on Another
convement way to pre set statxons IS to first tune manually to a sequence of deslred pro
grams and then for each statxon) yust move the nearest contactor over to fit on the control
disc gap The statlons wxll repeat as pre set so place the proper index letters on each button
